Custom Automotive Overmold Components with Precision & Durability
High-Performance Vehicle Parts Go Precisely
It is durable, ergonomic, and made of multiple materials, and has been in high demand in the automotive industry. Automotive overmolding is one of the solutions to these requirements because it involves the combination of thermoplastics, elastomers, and silicone rubber in order to create soft-touch, functional, and aesthetic parts. This is also known as automotive rubber overmolding, automotive plastic overmolding, or overmolding automotive parts, and is a highly advanced process that enables the manufacturer to create intricate designs within a single, continuous part.
SunOn, a worldwide well-known professional overmolding firm, provides custom overmolding service custom-made with a high volume production with irreproachable accuracy. Learn about their business at SunOn Mould.
What is Overmolding in the Automotive Industry?
Automotive overmolding is molding over a hard substrate on a thermoplastic or metal, usually to create bi-material or multi-material parts. The technology improves grip, tactile comfort, and durability, and minimizes assembly processes and production costs.
Key Advantages:
- Multi-material automobile overmolding of ergonomic and functional designs.
- Steering wheel, pedal, and dashboard overmolds made of soft touch.
- In-mold bonding guarantees continuous bonding of materials.
- Improved chemical, wear, and heat resistance.
- High-volume production of cost-effective dual-material automotive molding.
To produce high-performance automotive components of global standards, SunOn uses thermoplastic elastomer (TPE) overmolding and silicone overmolding to manufacture vehicles.
The Materials Used in Automotive Overmolding
It is important to select material to manufacture automotive overmolding with high precision. SunOn operates with the most diverse materials that guarantee the best performance:
- Thermoplastics (ABS, PC, PP): Have structural integrity.
- Elastomers (TPE/TPU): Have a soft-touch feel and flexibility.
- Silicone Rubber: Biocompatible, heat-resistant rubber, can be used as an internal component.
- Polyurethane (PU): Strong, impact-resistant over moulds.
- Rubberized Surfaces: Improve ergonomics and beauty.
SunOn makes use of hard-soft material automotive molding and multi-shot automotive molding to achieve high adhesion strength and dimensional accuracy in each component.
Uses
The use of overmolding is common in interior and functional parts of automobiles:
- Interior Components
- Comfortable and control steering wheels.
- Soft-touch gear shift knobs.
- Footrests and pedal covers to increase ergonomics.
- Aesthetic and user-friendly Dashboard soft-touch panels.
- Exterior & Functional Parts
- Door handles and trims
- Seals and gaskets
- Cases over electronic and sensor equipment.
Specialty Applications
- Soft touch keypads and buttons.
- Parts of wearable automotive devices.
- OEM overmolding of rubber-to-plastic.
These applications serve to point out the flexibility and worth of tailor-made automotive over-molding to the current cars.
Technical Innovations
SunOn combines the latest technologies to produce high-quality automotive overmold parts:
- Two-shot automotive overmoulding: Successive injection of soft and hard materials.
- Dual-material automotive molding: Thermoplastics and elastomers.
- Automotive bi-material injection molding: Ensures easy adhesion.
- Thermoplastic elastomer (TPE) overmolding: It is suitable for the ergonomic grips of buttons.
- Silicone vehicle overmolding: Improves durability and chemical resistance.
- Optimization of overmolding in the automotive industry: Cuts the cycle time and increases consistency.
Such innovations enable soft-touch, ergonomic automotive parts and bespoke overmolded automotive parts to be manufactured to OEM production with unsurpassed accuracy.
Overmolding Process in SunOn (Automotive)
Quality at all stages of overmolding:
Design & DFM Analysis
High-tech software is used to test the feasibility of components when it comes to automotive overmolding applications, making sure that the adhesion and material compatibility are optimized.
Mold Fabrication
Multi-cavity production is carried out using precision steel molds to aid in dual-shot and multi-shot automotive molding to ensure consistency in large volumes.
Material Preparation
Elastomers, TPE, silicone, and thermoplastics are well prepared so that they are soft-touch performers in terms of performance and durability.
Trial Runs & Production
The early experiments confirm the functionality of the mould and tight tolerance molding. Mass production is followed by optimization of cycle time to achieve cost-effective and high-quality production.
After Processing and Quality Control
Components are trimmed, de-flashed, and closely examined to ensure dimensional accuracy and high adhesion strength.
This is a multi-stage method used to provide automotive over-molding of high precision to both the interior and exterior vehicle components.
Comparison of Automotive Overmoulding and Other Methodologies
Overmolding Versus Insert Molding:
Insert molding inserts previously designed components into a mold, whereas overmolding uses soft materials over a substrate to enhance adhesion.
Overmolding Vs. Traditional Molding:
Less assembly, increased touch, and dual-material car overmolding of ergonomic grips and soft-feeling surfaces.
Benefits:
- Economical when production is in large quantities.
- Helps shape complicated geometry.
- Fits perfectly with soft-touch car overmolds and functional car parts.
