Our overmolding and insert molding processes produce custom prototypes and on-demand production parts in as fast as 15 days. We use aluminum molds that offer cost-efficient tooling, producing parts from a range of thermoplastic and liquid silicone rubber materials.

Overmolding and insert molding are frequently used for:

  • 少量生产零件
  • 桥的工具
  • 试点运行
  • 功能原型和测试

  • Height may be limited if using a silicone as the overmold material, and deeper parts are limited to a smaller outline.
  • 最小部分体积为0.025 cu. in. (40.98 cu. mm).
  • With substrate molds, we can maintain a machining tolerance of ±0.003 in. (0.08mm) with an included resin tolerance that can be greater but no less than 0.002 in./in. (0.002毫米/毫米).
  • 与热塑性overmolds, 公差与基板模具相同, 然而, 如果overmold是LSR, 然后公差移到0.025 in./in. (0.025mm).

Overmolding材料结合

Chemical bonding between overmolded materials is possible, but material compatibility should be considered in order to achieve desired bond strength. Incorporation of an adequate mechanical bond is strongly recommended if bonding is critical to your application. An undercut is a good example of a mechanical bond.

插入成型能力

Instead of a mold that produces a final part using two separate shots like overmolding, insert molding generally consists of a preformed part—often metal—that is loaded into a mold, where it is then overmolded with plastic to create a part with improved functional or mechanical properties. We currently accept inserts from PEM, Dodge, Tri-Star, Spirol, and Tappex. 完整的图表 stocked inserts at 金沙9999js is available here.

One way insert molding is used is with threaded inserts, which reinforce the mechanical properties of plastic parts’ ability to be fastened together, 特别是重复装配. Bushings and sleeves are another great way to increase part durability for mating components that need more abrasion resistance due to moving parts.

什么是Overmolding?

与overmolding, the production of the substrate parts is a standard injection molding process involving an aluminum mold with no heating or cooling lines running through it. 循环时间长一点, which allows our molders to monitor fill pressure, 化妆品的担忧, 以及零件的基本质量. When the total run of substrate parts are molded, overmold tooling is then assembled to the press. The substrate parts are placed by hand into mold where each part is overmolded with either a thermoplastic or liquid silicone rubber material.

什么是嵌件成型?

Insert molding is a similar process but instead uses a preformed part—often metal—that is loaded into a mold where it is then overmolded with a thermoplastic resin to create a final component. When the run is complete, parts are boxed and shipped shortly thereafter.
