what is overmolding mold?how many steps for the overmolding part?
Some molds allow previously molded parts to be reinserted to allow a new
plastic layer to form around the first part. This is often referred to as overmolding. This system can allow for
production of one-piece tires and wheels.
Two-shot or multi-shot molds are designed to “overmold” within a single
molding cycle and must be processed on specialized injection molding machines
with two or more injection units. This process is actually an injection molding
process performed twice. In the first step, the base color material is molded
into a basic shape. Then the second material is injection-molded into the
remaining open spaces. That space is then filled during the second injection
step with a material of a different color

Maching accuracy can be controlled at around 0.0025mm, processing size
upto 1020×610×610mm.
High-precision grinding machines are the necessary equipment for precision
molds. The company implements a quality strategy. The gringding machines are
high-precision grinding machines (precision upto ± 0.002mm, higher than the
processing center). Milling machines are imported from Taiwan, 4 of which are
equipped with automatic loading and unloading systems. They are powerfull,
precise and accurate. EDM machines and CNC wire cutting can cut slope and taper
exactly.
