LPMS is the first company to apply hot runner in low pressure molding technology. Hot runner system can eliminate runner and reduce the gate mark. It is designed for high volume production.

LPMS provides hot-runner systems like LPMS and Synventive(US). All components of the system made by the CNC machinery. The advantage are as below:

● Reduce the resin consumption

Hot-runner system eliminates runner and saves runner material. The saved resin will worth the hot runner tooling after 2 or 3 month production.   

● Improve product quality

Compared with common mould, the resin in the hot runner system stays humidity,flows more smooth, which enable it to overmold big size,thin resin wall products. The product after overmolded has low residual stress,small deformation. The hot-runner system has smaller injection gate which make the after overmolding product looks better.

● No need secondary processing,save labor cost.

After overmolding,the product can be separated with the tooling sprue area automatically. No need to get rid of the runner material and lower labor cost.

● Shorten the injection time,improve productivity

Hot-runner system helps in pressure transmission and requires lower injection pressure and lower injection/holding time. Shorten the

cycle time.

● Improve overmolded products consistency

Hot-runner system can balance the tooling filling process through the temperature control and controllable hot nozzles and makes the overmolded products consistent and accurate.
