#overmold #vs #insert #mold
Premium provide overmolding injection service over 20 years, overmolding is called 2 times injection molding, the production of the substrate parts is a standard injection molding process involving an normal mold with no heating or cooling lines running through it, which is a more rigid plastic and is designed to accept the second shot, normally the overmold is composed of a softer and flexible plastic like rubber.
How Does Overmolding Injection Molding Work?
The first shot is called substrate, is usually composed of a more rigid plastic, the second shots called the overmold.
The cycle time of overmolding is a bit longer, our experienced molders will monitor the cosmetic concerns, fill pressure and basic quality of the parts.After the substrate parts are molded, the overmold will be assembled to the press and the substrate parts will be put by hand into the mold and overmolded with rubber material or thermoplastic.
Advantages of Overmolding Injection
Cut Costs
Reducing secondary operation, assembly and labor costs.
Tough
Plastic overmolding components ensureproper alignment, prevent loosening and the plastic resin can provide improved resistance to vibration and shock, Parts produced are waterproof, shock resistant and airtight.
Reliability
Eliminating bonding step in the manufacturing process, improving components reliability.
Flexibility
Custom plastic overmolding allows for production of parts molded of multiple thermoplastic materials, enhancing design flexibility and multi-material components.
Application for Overmolding Injection
Overmolding injection has a wide range of applications, including:
Parts with soft grip handles
Window reveal moldings
Medical and healthy devices and instruments
Knobs for controls , appliances and assemblies
Encapsulated electrical components and electronic devices
