Co-Injection Hot Runner

A co-injection hot runner is an injection molding melt distribution system designed to enable the simultaneous injection of two different materials through a single gate into a mold. In a typical setup, a 'core' material is enveloped by a 'skin' material. This dual injection process is controlled and precise, ensuring consistent and high-quality products.

Co-injection Possibilities

PCR Core with Virgin Skin: Achieve the perfect balance between eco-conscious manufacturing and high-quality finish. This combination utilizes Post-Consumer Recycled (PCR) plastics at the core, enveloped by a virgin material skin. The result? Beautifully finished products that friendly to the planet and your budget.

Cosmetic Skin with Foamed Core: Elevate your products with our lightweight solution. By pairing a visually appealing cosmetic outer layer with a foamed inner core, achieved through chemical blowing agents or nitrogen injection, we create parts that are not only stunning but also lighter and more resource-efficient.

High-Strength Skin with Flexible Core: Ideal for parts requiring a tough exterior with shock-absorbing properties. This combination offers resilience and durability without compromising on weight or cost, ensuring your products stand the test of time.

Clear Skin with Colored Core: Perfect for creating parts with a vibrant pop of color encased in a crystal-clear exterior. This option combines aesthetic appeal with functional design, allowing for dynamic visual effects and branding opportunities.

Contribution to a Circular Economy

Reduced Waste and Resource Conservation:

By using PCR material, co-injection hot runners promote the re-use of plastic waste, thereby reducing the need for new raw material production and minimizing waste sent to landfills.
Sustainable Production:

Co-injection molding with PCR supports companies in their sustainability goals. It enables the creation of new products from old, contributing significantly to a closed-loop, or 'circular,' production model.
Market Opportunities:

As consumer demand for sustainable products grows, manufacturers using co-injection hot runners to incorporate PCR materials are well-positioned to access new market opportunities. They can offer products that meet high environmental standards, which is increasingly becoming a competitive advantage.
Regulatory Compliance:

As regulations around the use of recycled materials in production become more stringent, co-injection hot runners that allow for the seamless integration of PCR materials can help manufacturers stay ahead of the curve and maintain compliance.
