General Introduction
The solid silicone rubber injection molding machine is extensively used for the injection manufacture of solid silicone rubber products, the production efficiency and material utilization of which are greatly higher than the mould pressing equipment.

Compared with the common similar devices, this product is fitted with silicone rubber stuffer used for pushing the solid silicone rubber into the charging barrel. The stuffer is installed at the left side of the injection unit, assisted by the hydraulic cylinder for corresponding actions.

In addition, this equipment is superbly optimized on the basis of traditional models and according to the processing characteristics of solid silicone rubber products. The optimized items include the stuffer, valve and the relevant software. This solid silicone rubber injection molding machine is ideal for manufacturing sealing elements, automobile lifting lugs, composite suspension insulators, supporting insulators, etc.

Basic Product Features
1. This solid silicone rubber injection molding machine is configured with plasticizing and injection units dedicated for the silicone rubber.
2. The screw possesses optimal exhausting, delivering and plasticizing functions.
3. The feeding device is extremely safe and pre-alarm is available for starved feeding. Double-hand manipulation is recommended.
4. The hydraulic system is high-efficiency and low energy consumed.
5. We adopt the high-efficiency KEBA control system.
6. Electrical elements of Schneider and hydraulic elements of Rexroth are applied.
