China Over Molding Plastic Injection Mold Suppliers | Quality Factory Manufacturing for Dual Material Components
The Characteristics Of The Overmolding Mold
Ensure that the bonding area between hard and soft glue is tight and seamless, avoiding overflow or poor bonding.
It is necessary to precisely control the injection sequence and flow rate of two different materials to achieve the ideal encapsulation effect.
Due to the different characteristics of the two materials, the requirements for mold temperature are also different, and precise temperature control is required to ensure molding quality.
Key Design Points of Overmolding Molds
The fitting tolerance between hard and soft plastic components must be extremely precise to avoid plastic overflow or detachment.
The sealing position should be designed appropriately to ensure that the soft plastic can completely encapsulate the hard plastic without generating bubbles or gaps.
The locating pins and guiding system in the mold must ensure the accurate position of the hard plastic components during the second injection molding process.
Design efficient cooling channels to ensure rapid and uniform cooling of the mold, reducing cycle time and part deformation.
The Advantages Of Over Injection Molding Mold
For example, some tool handles, electronic product casings, etc., the outer layer of soft glue can provide a better grip.
Such as sealing, shock absorption, anti slip, etc.
By combining different colors and materials, the product becomes more attractive, while also enhancing its impact resistance and wear resistance.
