Injection Molding Processes
With cost-effective and high-quality to produce plastic parts, the process is a plastic or resin material heated to the melting point, then injected into the mold cavity and formed. Once it cools, the parts will be released from the mold. Repeat hundreds or more thousands of times, then you will obtain a large volume of injection molded parts.
The most cost-effective way to make a plastic part at scale and offers consistent quality for low-to-high volume manufacturing
Create a single part by combining two separate or more during molding but complimentary thermoplastic materials
Embedding secondary parts into the plastic injection molding process, the most popular metal threaded inserts and bushing
Allow for coloring or transparency in the finished product, highly suitable for products performance, durability and high quality are a necessity.
HundMold Quality Inspections
Quality is key when it comes to injection molding parts, so why not make sure you're getting the best product? With a variety of inspections processing assure that your parts will be up to all standards.
Plastic Injection Molding Finishes & Materials
From the smoothness of glossy plastics to the rugged durability of fiberglass, plastic injection molding is a versatile option for creating products with numerous finishes and materials.
