Keys of the Success for LSR Molding

“ Flow balance” and ”Thermal balance” is the key for successful LSR injection molding.

Ann Tong industrial company is well known LSR cold deck provider with inexpensive price and match the above successful factors. Not only provide valve gate cold deck, but also provide 90% finished mold (User only need to make cavity core only). We also offer the thermal analysis to do DFM (Design for manufacturing) for reference.

We provide customer satisfied cold deck for water proofing LSR molding.
(P+R, M+R, R+R )

The applications of Liquid Silicone Rubber (LSR) have gradually increased due to its excellent property and weather ability. We provide the high performance LSR cold runner system and cold deck to the industries in the electronics and appliances, construction, automobile and medical products, etc. The common used products include pacifier, medical equipment, kitchen utensil, headset, buttons, seals and dive masks, etc.

In order to provide our customers a high performance and quick delivered LIM cold deck system. We put a lot effort to innovate the LSR cold runner system. From our experience, the use of LSR parts and insert molding process (plastic or metal with LSR) are growing up rapidly in the near future and requiring the flow balance strictly. Simultaneously, we develop the valve gate cold deck system with flow control that can be adjusted during molding process and easily getting a balance flow for each nozzle and gate.

Liquid Injection Molding (LIM) process

Amold LSR cold runner system is a valve gate system and installed in the mold. It will support customers to increase production and quality.

The characteristics are as followings：

1. Valve gate nozzle：	Direct injection molding onto the product surface, no slug, decreases the material cost and increase the profit.
2. Cold deck：	The modular design, the quick Installation and easy to maintain.
3. Thermal analysis：	Mold heating system, to guarantee the mold temperature uniformity.
4. Excellent insulation：	Analyze the cooling system before making cold deck and ensure great heat isolation effectiveness.
5. Flow control valve：	Apply to multi-cavities and get flow balance to have the stability of the production and good product quality.
6. Temperature alarm：	The device can alarm while the system temperature rising over the setting temperature to prevent silicone solidification.
