TPE Overmolding Service | Custom Thermoplastic Elastomer Solutions
TPE Overmolding Service: Thermoplastic Elastomer Solutions of SunOn
In the current competitive manufacturing environment, the provision of products that can withstand wear and tear, comfort, as well as beauty has become important. TPE overmoulding service offers a solution unmatched by other industries such as electronics, automotive, and medical equipment.
- The overmolding of thermoplastic elastomer (TPE) enables manufacturers to create soft-touch, high-performance parts with complex geometries in one process, and hence reliability, functionality, and high user experience.
- After years of experience and well-developed manufacturing abilities, SunOn has already become a professional manufacturer of TPE overmolding, offering high-quality and economical solutions to the tasks of various industries.
TPE Overmolding Benefits
TPE overmolding is an advanced technique through which a thermoplastic elastomer is molded onto a secondary substrate, which is typically a plastic or rigid material. This injection, which uses a dual material, leads to the creation of parts with better grip, shock-absorbing features, and durability without compromising on the appearance.
The major benefits of TPE overmolding are:
- The soft-touch surface finish is the best option in ergonomic products.
- Dynamometer and Vibration resistant to industrial and automotive applications.
- Harsh environment, chemical, and temperature resistance.
- Continuous connection of multi-material designs without assembling.
- Even complex parts have high-dimensional stability and accuracy.
The experience of TPE overmolding service of SunOn guarantees that all products are high-tech and can provide the same output with the same performance of electronics housings, automotive parts, medical equipment, consumer products, etc.
Steps of TPE Overmolding
The TPE overmolding production part by SunOn involves the use of great design, tooling, and precision engineering, which has been successful in producing a perfect outcome. The process can be divided into the following details:
- Material Choice and Compatibility
It is essential to select an appropriate TPE compound and substrate material. SunOn considers mechanical, thermal, and chemical compatibility to achieve good adhesion and performance.
- Mold Design and Engineering
Design of TPE molds is a requirement of high-precision molding. SunOn's engineers optimize:
- Gate positioning, runner system engineering.
- Multi-material molding Mould cavity.
- Optimization of cooling channels to improve fast cycle times.
- Durability Mold steel selection (H13, S136, P20)

Injection Overmolding
In the TPE injection overmolding service, TPE molten is injected into the mold on top of the pre-molded substrate. Temperature, pressure, and cycle time are process parameters that are carefully checked and monitored to guarantee ideal adhesion and dimensional precision.
Quality Control and Testing
SunOn also engages in intensive adhesive testing, bonding strength tests, and tolerance tests. This ensures that all the TPE overmolded components are within customer requirements, as well as the industry standards.
