Evco Plastics: Technology

Stack Molds

stack mold EVCO has expertise in building and running stack molds. Stack molds consist of multiple parting lines that allow for maximized utilization of the machines.

Multi-Shot Molding

two-shot molding In this process, polymers from two injection units are applied through independent nozzles on one press to produce pieces like soft-touch handles or two-toned automotive light lenses.

In-Mold Decorating

in mold decorating A pre-printed or decorated appliqué is inserted into the mold cavity prior to the injection molding process to create a decorated part.

Over Molding

over molding Utilizes two separate molds on conventional presses to overmold one part to another for unique visual or ergonomic appeal such as handles.

Insert Molding

insert molding Allows a metal insert to be embedded in a part in one operation for improved product structure and increased strength.

Gas Assist


Injecting molten plastic into a mold is assisted by a pressurized gas, which pushes the plastic into the extremities of the mold while hollowing out the thicker sections in the part.

Automation/Robotics

automation and robotics EVCO manufacturing operations take full advantage of programmable servo-robotics to ensure efficiency and product consistency. Our automatic assembly cells provide for the sequence of manufacturing steps and assembly in a contained process. This ensures process repeatability and reduces part-to-part variations.

Contract Manufacturing

contract manufacturing EVCO has the resources available to provide our customers with a final assembly. With our global sourcing, we are able to purchase the components required, mold and assemble the parts to provide a complete end product.

Value Added Assembly

value-added assembly and decorating EVCO works with our customers to provide an assembled and decorated product.
