Our Injection Molding Process
Our injection molding process is designed to be simple, efficient, and easy to understand, even for first-time buyers. Every project follows a step-by-step approach that ensures quality and consistency.
We start with design review and requirements analysis. Our engineers evaluate part geometry, material selection, and performance needs to ensure the design is ready for manufacturing. Early feedback helps prevent costly changes later.
Next, we move to tooling and mold development. High-precision molds are designed and manufactured to meet your specifications. Each mold is tested and validated to ensure durability and repeatability.
After tooling approval, we conduct sampling and testing. Prototype plastic injection molding in South Dakota allows clients to review parts before full production. Any adjustments are handled quickly and efficiently.
Once approved, production begins. We manage molding, inspection, packaging, and logistics under strict quality controls. This structured process ensures that LXG Injection Molding delivers consistent results for every project, from small runs to large-scale manufacturing.
