Large Part Injection Molding
Large Part Injection Molding
Large part injection molding is a complex process that requires specialized equipment and expertise. Our team has extensive experience in plastic molding large parts across a variety of industries. We’ve upgraded our high-tonnage machines with extended-capacity injection units and reinforced tie-bars so they can reliably fill and clamp very large molds.
- Injection molding machines with a range of 450 to 1100 tons;
- Automated robotic arms for consistent, accurate part handling;
- Custom mold design and manufacturing capabilities;
- High-quality surface finishing options for a refined finish;
- Comprehensive assembly services to integrate complex components;
- In-depth testing and rigorous quality control processes;
- Flexible production runs for both small and large volumes.

Optimizing Large Part Injection Molding Process
We design and produce all the mold in house, our facility is equipped with mulit-axis CNC center and EDM equipment to create high-precision molds that can handle high-tonnage injections, essential for large parts.
We use hardened tool steels, normally P20, 718H or upon request, to ensure longer mold lifespans, often exceeding 300,000 cycles. Furthermore, once the mold worn out, we will build a new set of mold with no extra fee your side.
2. Design for Manufacturability (DFM)
We work closely with your design team to identify and address potential production challenges early in the process. By assessing your large part designs for manufacturability, we help optimize designs to minimize production difficulties, reduce material waste, and lower overall costs.
Our DFM analysis includes suggestions for design adjustments that make molding easier and more efficient.
3. Material Selection
Choosing the right material is crucial for ensuring that your large parts meet performance requirements while being manufacturable at scale. We offer an extensive range of engineering-grade thermoplastics and elastomers such as ABS, PC, PP, TPU, etc., that are ideal for large parts, with properties such as strength, flexibility, and impact resistance.
We also provide expert guidance on material modifications using additives to enhance specific characteristics like UV resistance, flame retardancy, or improved tensile strength.
4. Finished Part Assembly and Testing
We offer complete finished part assembly services, ensuring all components are accurately aligned and securely joined. Our team pays close attention to the precision and fit of each part during the assembly process to guarantee optimal functionality.
In addition to assembly, we conduct a range of tests to validate that the assembled parts meet required performance and durability standards. This includes compatibility checks, strength assessments, and functional testing, ensuring that each final product performs as expected.
