OUR CUSTOM PLASTICS FABRICATION CAPABILITIES
At Cooper Plastics, we offer numerous plastic fabrication methods to meet the unique needs of our clients. From complex, innovative designs to large-scale production, our manufacturing process is designed to take your projects from concept to reality with precision and efficiency. Explore our diverse plastic manufacturing capabilities below!
Raw plastic material (resin) is processed into flat sheets that can be used in other plastic manufacturing processes.
Heat and pressure are used to force plastic sheets into a mold and transform them into the end product.
In this process, also known as rotomolding, the mold is rotated vertically and horizontally in an oven to produce hollow plastic products.
Molten plastic is injected into the mold to produce durable plastic products and minimize scrap material.
Compressed air is blown into a plastic tube (parison/preform) within the mold to produce hollow plastic parts and products.
This process combines traditional injection molding with a foaming agent to create parts with a foamed core and solid outer skin that are lightweight but durable.

WHAT IS CUSTOM PLASTICS FABRICATION?
Custom plastics fabrication is the process of designing and creating plastic components tailored specifically to meet the unique requirements of a project. Unlike standard plastic manufacturing, which produces generic items in bulk, custom plastic manufacturing allows for customization of size, shape, material, and functionality. This production process ensures that the end product aligns perfectly with the client’s specifications, whether it’s for industrial use, consumer goods, or specialized equipment.
At Cooper Plastics, our approach to custom fabrication is to combine the skills of our craftsmen with high-quality materials and advanced manufacturing technology. We start by reviewing your needs and the specifications of your project. From there, we collaborate to choose the materials and manufacturing techniques that will produce the desired results within your budget. Once all the details are finalized, we’ll get your job scheduled for production. Our experts are committed to quality and ensure every piece we fabricate not only meets but exceeds your expectations.
