Foam Injection
Product Introduction
Shaping Foam into Complex, Ready-to-Use Parts
EVA GLORY provides end-to-end foam injection services – from material development to final production. The process begins with injection-grade foam pellets (EVA, PE, or blends), which are heated until soft inside an injection molding machine. The softened material is then injected into a high-precision metal mold under pressure, taking the shape of the final product. This method is especially suited for producing curved, contoured, or hollow components that are difficult to achieve with traditional cutting or thermoforming.
Custom Compounds
We formulate foam materials specifically for injection molding and your performance goals. Options include our proprietary Nitrex for shock absorption, DeCO2 biobased foams, and specialty blends with added functions like antibacterial, flame retardant, UV-resistant, or ESD-safe properties. Each compound is fine-tuned for the right balance of flexibility, durability, and density.
Design Support
Our team works closely with you from the start – whether you already have a product concept or need help developing one. We provide OEM, ODM, and JDM support, including design consultation, foam behavior analysis, and moldability checks. This helps ensure your part meets both functional requirements and cost efficiency before moving to the next phase.
Prototyping
We accelerate product development with two levels of prototyping. For quick form verification, we use 3D printing to validate shape, fit, and ergonomics. When material performance needs testing, we apply conventional molding to simulate how the final injected foam will behave. This dual approach helps catch issues early, shortening lead times and minimizing rework.
Mold Tooling
Based on your part design and selected foam material, we build custom molds optimized for consistent results. This includes determining the best cavity layout – single for small batches or multi-cavity for large runs – and adjusting for how the foam expands, flows, and cools. The goal is to create tooling that supports efficient, high-quality production from the first shot.
Production
With the mold finalized and materials approved, we move into full-scale foam injection. This process shapes your custom compound into finished parts with high precision and repeatability. Compared to traditional cutting or thermoforming, foam injection offers faster cycle times, reduced material waste, and excellent consistency – especially for curved or complex designs.
Whether you’re developing protective gear, sporting goods, or other precision foam components, EVA GLORY’s foam injection service offers the expertise and support to bring your ideas to life – efficiently, accurately, and at scale.

Production
Foam injection is ideal for producing complex structures, such as curves and spheres that are difficult to achieve while using conventional converting techniques like thermoforming or CNC process, which can be both time consuming and cost intensive. Using foam injection not only increases production output with faster cycle time but also decreases the waste of raw materials.
