//什么是二次成型?
What is overmolding?
二次成型的过程包括将一组零件组合在一起,同时保证机械完整性,并抵抗各种恶劣条件,如磨损、冲击、辐射、化学品、温度和湿气进入。粘附效果很大程度上取决于所选材料的相容性。分子链相容性越强,粘附力就越强。
The process of overmolding involves joining together a set of parts while guaranteeing mechanical integrity and providing resistance to a variety of conditions such as abrasion, shock, radiation, chemicals, temperature and moisture ingress. The adhesion effect depends highly on the compatibility of the materials chosen. The more the molecular chains are compatible, the stronger the adhesion will be.
//为什么要二次成型?
Why overmolding?
二次成型为电缆/连接器接口(该接口传统上是电缆组件的最薄弱点)提供了坚固且定制的机械保护。
Overmolding provides robust and tailor-made mechanical protection for example for the cable/connector interface which is traditionally the weakest point of cable assemblies.
二次成型可用于许多其他目的,包括:
形状塑造
消除应力的网尾
密封:气密性、水密性
吸收重复弯曲
提供固定点
屏蔽终端保护(EMC)
改进线束的整体外观
An overmold can serve many other purposes including:
Shaping
Strain relief
Sealing: airtightness, watertightness
Absorption of repeated flexes
Provision of fixing points
Protection of shielding termination (EMC)
Improvement of the overall look of the harness
通过定制形状节省空间
更容易将链接或部件集成到客户系统中
与标准化连接器相比,定制端子包覆成型具有更高的性能
在电缆组件中集成电子功能(如信号转换)
定制互连解决方案
Space saving with customized shapes
Easier integration of links or parts into the customer’s system
Customized contact overmolding for higher performance compared to a standardized connector
Integration of electronic functions (e.g. signal conversion) in cable assemblies
Customized interconnect solution
