As rubber manufacturers know, once ACM is compounded by adding accelerator which is ready for curing process, its effect cannot last for one more week and its shrinkage rate is changing day by day so usually is hard to be controlled in production.

This is another example which we study Silicone as the material of cooling sheet used in electronic components.

L&J is able to design formula to fit specific compound property requirements.

Basically compression cavity mold is used for production of oil seal or some kinds of circular rubber part with suitable structure to make. We have good facility in mold-production, design and measurement.

Compression molding process is directly arranging rubber strip above cavity then close mold plate to proceed molding process. Besides the relative production parameters, the mold design focuses on how to have molding pressure spread averagely and how to deal with the going of waste rubber and exhausting air. Furthermore, less flash is always the essential requirement which depends on the design of cutting groove. With good design of cutting groove, not only flash can be easily erased manually, but also can produce good flash-less rubber parts. Cutting groove is also related to the mold life time. The selection of mold steel is an important consideration.

Transfer injection molding process is arranging rubber strip on a chamfer mold plate, then leads the rubber flow into injection channel to fill up cavity averagely through compression molding process. The most common rubber part which uses this kind of mold design is valve stem seal or bonded seal. But anyway, L&J will give the best suggestion according to the structure of rubber part which you want to produce.

Injection molding process is using rubber injection machine to inject rubber compound into mold cavity. The advantage of this method is to save rubber compound and flash-less. However, not all of rubber parts are suitable for this method. L&J will give the best suggestion according to the structure of rubber part which you want to produce.

L&J has some existing oil seal specification in stock which can afford the small quantity purchase order.

L&J is able to provide full sets of international standard size O Ring of AS568 system, JIS G system, JIS P series, JIS S system.

O Ring kit is a specific combination of different O Ring size which is collected for specific applications.

This is a special O Ring product range which L&J work for OEM or customized requirements.

Well molding quality with flash less, tool mark less and easily to be trimmed manually.

Well molding quality with flash less and easily to be trimmed manually.

This is what L&J is good at. Here we would like to introduce some special cases we produced for customers in practice.

The main cooperation between L&J and G-Way is that L&J is the mold supplier to G-Way and G-Way is the source and consultant of rubber trimming & inspection machine to L&J so they make up to each other in coordination and provide & share resources.

L&J sells two kinds of rubber accessory processing machine : one is SEAL ADHESIVE APPLYING DEVICE MACHINE and the other is SEAL SHELL AIR-DRY ROTARY MACHINE. In the future, we will continuously develop other new items for customers.

L&J supplies engineering plastic for customers as a kind of engineering material to different industrial machining application.

From the past experience, L&J has good ability in developing die casting molds and parts for customer. The working factory are located in middle Taiwan and quality always obtains much favor from Japanese, India, and Middle East customers. The following pictures are examples which L&J once made.

In the earlier stage, L&J tried to expand business to motorcycle components. The best items which L&J has built up with a very good foundation is roller chain. It is divided into 2 fields: Motorcycle Chain and Industrial Chain.

The main cooperation between L&J and TY is that L&J is the mold supplier to TY and TY is the source and consultant of rubber machine to L&J so they make up to each other in coordination between mold and rubber machine and provide & share resources.
