Metal stamping manufacturer in Johor, Malaysia completes the acquisition of factory

What started out as opportunistic move over a year ago has turned strategic now, as Demand Options, Ge-Shen Corporation Berhad’s metal stamping unit is able to fully utilize the space in the new factory. With increased capacity, it is able to serve more customers in the supply of precision metal stamping parts around Johor, Malaysia and rest of the world.

First announced 2 May 2018, Demand Options rented the property with an option to purchase. This gave flexibility to the management to organize its finances and operations to do its production planning. However, as business ramps up, the Management took a view that exercising the option to purchase early was more beneficial – financially and strategically as major improvements were to be made to improve the property.

Today, the transaction has completed.

Expanded metal stamping facility
The new facility is directly neighboring Demand Options’ current facility

Extending Metal Stamping Capabilities

Demand Options has been in the metal stamping and sheet metal fabrication since 1997 in Johor, Malaysia. Previously growth has been hampered by the lack of space as it was challenging to make incremental capacity increases in another site. Following this acquisition, Demand Options has ordered a further 13 units of metal stamping machines of various size. This increases its metal stamping machines from 20 to 33 units (+65%). Some 7 units has arrived and the rest is expected to arrive in the coming months.

New metal stamping has arrived the Johor facility
The machines are arranged in such a way that robotic arm transferring is possible: reducing takt time, cycle time and overall costs.

Renovation on the new site has started earlier in the year, just as enquiries for metal stamping parts has picked up. With ample space now, the Management is confident that it will be able to make specific and concentrated investments into further capacities where required.

Demand Options can perform various different processes, for example, both progressive and single functions, spinning, riveting, tapping, CMT welding etc.

Growing together

Ge-Shen has been in expansion mode over the past years and is continually looking at various options to continue growing.

Overall, Ge-Shen now occupies more than 550,000 square feet of factory space in 4 different sites in Johor, Penang and Hanoi. Ge-Shen aims to continue developing capabilities in order to serve customers better.

Ge-Shen is looking for various business development opportunities and welcomes and any enquiries.

Celebrating 13 years of injection moulding in Hanoi, Vietnam, Ge-Shen introduces a new 650 tonne machine

A new 650 tonne injection moulding machines arrives in Ge-Shen Vietnam, bringing total machines to 46.

Humble beginnings

Ge-Shen Vietnam Co. Ltd incorporated on the 30th June 2006 had humble beginnings of having only 10 machines for the provision of injection moulding services.

It wasn’t smooth sailing all the way – in 13 years the operations moved twice. The first to downsize, back in 2010, as demand wasn’t as large as earlier anticipated. But this time – the second time, the move was with much better sentiments, as demand increased.

Having operated in extremely challenging environment in the past, the management team has learned valuable lessons on how to operate in Vietnam. These experiences, which cannot be bought, ultimately forces the management culture to be lean. Ultimately, the team has also learned the universal need to listen to its customers and make specific and concentrated efforts in improving its services to be THE solutions provider.

Responding to the need to scale, in anticipation of growth potentials in the Hanoi region, and the need for improved facilities to make significant overall improvements, the senior management of Ge-Shen took a bold decision to acquire a piece of land and build a new manufacturing facility.

From 30 injection moulding machines to 46 in Vietnam

Ge-Shen Vietnam acquired a new land in the same industrial estate – Dai An Industrial Park in the Hai Duong province of Hanoi – measuring 16,008sqm in size. Upon the completion of the acquisition of land, efforts were immediately put in place to begin construction and renovation. The complete shift over to this new site was completed in September 2018. Now, Ge-Shen Vietnam has 10,759 sqm of manufacturing space and is capable to increase further machines for future growth.

Having moved to its new facility, it quickly acquired 8 more injection moulding machines in 2018. This June, its first injection moulding machine investment in 2019, is 650 tonne injection. This is the second 650 tonne machine for Ge-Shen Vietnam and is now operational.

Having settled down from the initial move for almost a year now, Ge-Shen Vietnam is expected to make further improvements to its facility in the 2nd half of 2019 . This is to improve its manufacturing flow and storage space. This will be accompanied by further targeted investments in injection moulding machines to increase specific capacities to meet future customer demands.

Injection moulding and more

The facility in Vietnam has still un-utilised manufacturing space, suitable for more injection moulding, other components manufacturing and assembly services.

Depending on specific customer requirements, it is prepared to continue investing in further, whether in injection moulding machines or assembly lines, to ensure total customer satisfaction.

Ge-Shen hopes to continue providing excellent manufacturing service to its customers in Vietnam and the rest of the world. Its vision is to be THE solutions provider via its dedicated efforts in providing engineering solutions and contract manufacturing services.

Ge-Shen welcomes any potential customer enquiries for new projects.

Ge-Shen Adds Liquid Silicon Rubber injection moulding process

With growing demand for liquid silicon rubber, especially in the medical, infant and baby care, electronics and industrial industry, Polyplas, a subsidiary of Ge-Shen has invested in Liquid Silicon Rubber (LSR) injection moulding capability and is ready to supply LSR products to its customers.

Why Liquid Silicon Rubber?

LSR injection molding provides consistent part quality and consistency as compared to other other elastomers and thermoplastics. It is able to achieve high precision, and if done well, is burr or flash free, direct from the mould.

Silicon rubber is tasteless and odorless, can be sterilized in a variety of methods and can be formulated to comply with FDA requirements. It is naturally resistant to bacteria growth, making it a perfect choice for medical devices and products.

It is durable, and can withstand extreme temperatures, fire resistant, water resistant and chemical resistant, making it very fit for industrial use. Its elongation, high tear and tensile strength, provides flexibility and durability and can be formulated to have hardness range of 5 to 80 Shore A.


Partners in mould making (or tooling)

While LSR is fairly new to us, we have various partners in the industry who has been producing LSR moulds (or tooling) for many years. The tooling they make can be of two types – open nozzles and shut-off nozzles. The choice of which to choose depends on the quality requirement and specific use. Our mould makers produces moulds which can guarantee burr or flash free finished products.

How we can help you

Medical Injection Moulding: 5 Things to Consider

Many injection moulding suppliers today have the ability to provide manufacturing services to the medical industry. But, is there more than just having injection moulding machines?

We have summarised 5 key things to consider when choosing a medical injection moulding supplier for your medical components and medical devices.

1. Environment

Depending on the product requirements, having suitable environment controls are important. Certain products are required to be manufactured in a clean room (like our Class-8 clean room), some in a controlled environment whilst others can be manufactured in any normal factory floor. It is essential to define this when searching for a medical injection moulding service service provider as cost and quality may vary.

Class 8 clean room provides dust free environment

2. Validation process

The IQ (installation qualification), OQ (operational qualification) and PQ (performance qualification) process basically ensures that the the medical injection moulding process meets the quality acceptance criteria for the product. Whilst not all medical device requires this validation process, it is important to specify any requirement to the supplier up-front. This is to ensure that they understand the requirements of the validation process and provide adequate attention to this while developing the manufacturing process.

3. Certification of the medical injection moulding partner

When considering suppliers, have a look at their quality systems. the most basic ISO 9001 certification should be mandatory to ensure that the supplier has an adequate Quality Management System. Depending on your requirements, medical devices that require FDA approval or more stringent quality requirements, ensure that they have ISO 13485 and are up to date. Not all medical injection moulding requires ISO 13485, therefore be sure to tell your medical injection moulding partner the requirements up front.

4. Suite of capabilities

For most medical device manufacturers, it is important to ensure that their vendors are robust enough to have most processes in-house. This applies as well to the medical injection moulding vendor. While engineering skill-sets, like the ability to carryout design for manufacturability (DFM), mold / tool making and project management is important, also ensure that they have ability to do secondary processes. This includes having processes like liquid silicon rubber moulding (LSR), printing, ultrasonic welding and assembly. The less outsourcing, the better to ensure processes and quality is controlled.

5. Data

We cannot stress enough the importance to have data. Whilst traceability is part and parcel of ISO 13485, having a Manufacturing Execution System (MES) helps the capturing of data in a more autonomous manner. Having a stable Enterprise Resource Planning (ERP), Document Management System (DMS) and data security policy and procedures will greatly help ensure digital security, traceability and storage of documents. Hence, choose a vendor who is willing to invest in these systems to ensure that your supply chain management can be digitalize in the future.

Management Discussion & Analysis 2018: A Summary

An extract of the MD&A for 2018. Full version can be found here


The financial performance of Ge-Shen Corporation Bhd (“GSCorp”) was less than satisfactory for the year ended 31 December 2018 with a 11% drop in revenue to RM202.35 million and a 58% drop in Profit After Tax to RM4.52 million. In terms of Earnings Before Interest, Tax, Depreciation, Amortisation and Forex (“EBITDAF”) – the measurement of normalised cash generation GSCorp managed to turn in RM20.60 million which at a drop of 35% is a slightly better outcome than the Profit After Tax numbers would have suggested. Over the past year the operating environment has progressively been more challenging with the US and China trade war, slowing global economies and shorter product life cycle all playing a role in creating a more challenging operating environment. The cost of doing business has also increased through higher electricity charges as well as employment costs as wages and other mandatory charges has increased over the past year.


The past year has seen some material increase in our cost of doing business such as that of employment costs as minimum wages were increased together with an increase in the levy on foreign workers. Electricity was another cost component that has increased. The unfortunate thing about these cost increases were that it came at a time of lower revenues and because of the already thin margins that manufacturers are operating under, it has a disproportionate effect on the profitability of the company.

Hence going forward in 2019 the Management is focusing on cost management and in making the operations more efficient and to generate less wastage. We will be committing more capital to factory renovations and floorspace relayout to improve operational efficiency as well as the introduction of more robotics into the manufacturing process. We will also align our business development efforts to securing more value adding jobs.


The Management believes that top line growth is something that we must pursue as if we don’t grow our capabilities, we will drift further way from the requirements of our customers, rendering us irrelevant very fast. Hence in this phase of GSCorp’s development, it is about resourcing up for growth through additions to the physical capital stock (i.e. land, building and machinery), additions to capability and processes (clean room and robotics), enhancements to the support systems (Enterprise Resource Planning System (“ERP”) and Manufacturing Execution System (“MES”)), and a commitment to build more customer linkages through more active business development programmes. We believe that in the short term, the period of the most extensive capacity building is almost behind us.


The most visible aspect of our capacity expansion can be seen from the completion of the new factory in Hanoi, Vietnam. While there was a delay in the commissioning of the factory until August of 2018 against the earlier expectation of May 2018, this was still nonetheless very judicious in terms of timing as the area around Hanoi has seen a huge increase in activities as Vietnam is seen as one of the places which will benefit most from a possible relocation of the global supply chain away from China. With a brand-new facility to showcase and capacity to sell into a market needing capacity, we are confident that this new plant will translate into an important asset of GSCorp in the coming years.


We have completed an ISO Class-8 clean room. Our clean room is outfitted with several specialised moulding machines and ancillary equipment to support our move towards meeting the manufacturing capabilities for the medical industry.


For the metal plant, the completion (of the purchase of factory) is necessary in order to facilitate the renovation of the plant for a dedicated metal stamping facility for a customer in the industrial sector. This is a new customer with much promise of higher volume parts, and we expect mass production to start in April with the arrival of new machinery. As for the plastic facility in Johor, we are relaying out the facility for a better aligned factory with potential for more automation and better work flow.


Revenue experienced a dip for the whole year (2018) and the bulk of the revenue dip occurred in the second half of the year when global economies turned from the coordinated growth to a coordinated downturn quite swiftly. This downturn in global economies was further exacerbated by the trade war between China and the US and these two factors contributed to the slowdown in the revenues of GSCorp. Sectors such as consumer electronics was particularly impacted with orders from several customers dropping off from the third quarter onwards and industrial products sector was also similarly affected as well. This is due to slower sales of the final product and the effect of inventory adjustment as principals sought to reduce stock through a decrease in ordering from their manufacturing suppliers like GSCorp. In certain products, principals have discontinued the running of certain models totally. The path to rebuilding the revenues is through an active business development programme.


Throughout most of 2018, Management has implemented a more comprehensive business development programme in order to complement the investment in the physical infrastructure space in an effort to grow. We have worked very hard to widen our network of customers as well as diversity in the sector exposure.

The role of business development is not just limited to having several sales persons on the ground to pick up leads, follow up on proposals and then having the lowest price on the quotation. The process of vendor selection is usually a long and sometimes torturous process as the principals assess the vendor’s capabilities in both hard ware and also engineering capabilities which is then audited before the engagement moves on to discussion on a particular part or model. In some cases, the manufacturer must also help the customer in interpreting their ideas into a product which can be manufactured efficiently without compromising on the quality of the product.

Therefore, having the right people to be able to deliver the solutions to our customers is key to the business development initiative. We are pleased to write that there has been some success in the business development side as we have been active in bidding for projects in all of our manufacturing locations.


This trade war and the accompanying narratives surrounding it, is increasingly seen as something more fundamental and long term, therefore from a business rationale approach, supply chains which have traditionally relied on the manufacturing of goods out of China for global consumers is now being reexamined. At a minimum, there is a growing urgency amongst brand owners and principals to have an alternative supply chain to counter the effects of the tariffs. To preempt further disruption in the future, procurement teams have been busy scouring South East Asia for quality and reliable manufacturers to provide an alternative to China based manufacturers. As a quality manufacturer in the South East Asia region, GSCorp has been a beneficiary of this increased activity, however we must caution that while there have been a lot of early engagement, substantive success has yet to be recorded. While the actualization of these potential may take some time, we can however count ourselves lucky in having made the right investment decision of investing into more manufacturing capability as well as the increased efforts in business development thereby enabling us to be an active participant at this stage.


GSCorp as a component supplier into the global supply chain needs to build scale in the business as scale is essential for us to be able to cover more customers in different segments in order to achieve a greater diversity in end customers, scale is also needed to be able to offer more specialist engineering-based solutions to our customers in order to build a longer lasting and stickier relationship. This scaling up encapsulates the building up of manufacturing capacity and capability. The need to scale up is one of the most important matrices on our basic philosophy as it not just a permissive factor in our ability to grow but also an ability to derisk the business through diversification.
