Plastics Manufacturing

Sun Industries starts out by applying your concept ideas to 2D or 3D designs to serve as a blueprint for your application to apply to our multi-step manufacturing process. To meet your specific requirements, we offer a variety of injection molding production types: single cavity, multi cavity, hot runner, and cold runner.

As part of our quality control process in tooling development, we offer specialized testing procedures to ensure the quality of your plastic components and guarantee ease of repeat production by utilizing our Sun Industries Maintenance Program to store your tooling privately and safely.

We also provide a wide range of assembly capabilities including hot stamping, pad printing, spin welding, ultra sonic welding, tapping, off-set printing, and overmolding to guarantee that your plastic components are completed to your exacting specifications.

We manufacture the highest quality plastic components in a time-sensitive manner. Our metal to plastics conversions and alternate plastics conversions ensures that our plastic components will perform and exceed the standards for your equipment.

Single Cavity

Single Cavity Molding involves a single-impression mold which produces only one plastic component at a time in a single cycle.

Multi-Cavity

Multi Cavity Molding involves a multiple-impression mold of a single item which produces multiple parts in a single cycle.

Hot Runner

Hot Runner Molding involves molten plastic being injected into the cavities of the mold. It is necessary to maintain the uniform heating of the plastic while the rest of the mold cools to solidify the component quickly.

Cold Runner

Cold Runner Molding involves a formed channel between the two halves of the mold, which delivers the plastic material from the injection molding machine to the cavities. The cavity is electrically heated and insulated from the cold chamber, which is cooled instead of heated. When the process is complete, the mold opens and ejects the new plastic parts and the material left in the runner.

We see every detail of your application to completion with our wide range of assembly capabilities including hot stamping, pad printing, spin welding, ultra sonic welding, tapping, off-set printing, and overmolding.

Controlling the plastics manufacturing process from beginning to end ensures that your parts will arrive to you with every detail completed to perfection, from size and fit to labeling and all customizations in between. When you receive your filter parts, you can rest assured that they will meet and exceed the level of quality that your customers have come to expect of your company down to the finest detail.
