SHIMI DC400T Cold Chamber Aluminum Die Casting Machine for making LED lighting
Mold clamping unit adopts Five-dot type toggle design, which optimized structure of connecting road and enhanced sports properties.
The steel bushing of hinge pin adopts alloy steel bushing (oil lubrication exist simultaneously),which reduce times of lubrication and prevent locking of toggle when no oil .
The optimization design of die platens have been carried out multiple times through analysis of element software, then strengthening design (increased thickness and support ribs of castings ), which both guarantee the service life of die platen and mold. The tie rods of each machine have passed the test by professional testing organization, to ensure the deflection of tie rod within reasonable scope during the operation of machine.
Using 17.5Mpa system pressure, the maximum dry shot speed reaches to 8-9.5m/s, the injection force increases about 5-8%, it is more easier to molding to products with thin wall or high requirement on air tightness and surface finish, to reduce porosity of die castings effectively , especially suitable for automotive castings and stress castings.
Central automatic lubrication system, timing lubrication toggle to improve mechanical life and reduce maintenance.
