China custom plastic injection molding & Manufacturing process details

Injection mold design
Clients provide 3D model design in STL format, our engineer converts the STL file into STEP format, then designs deep drawing mold according to the product’s design requirements, including water cooling systems, gate types, ejection methods, and Moldflow analysis.

Mold making
Making the injection mold according to the mold design, Using LKM mold base and standard mold accessories, the mold finished with 3 weeks by CNC machining, WEDM EDM, Assembly testing, the first testing samples were sent for clients confirmation on the fourth week.
