Plastic Injection Molding Hot Stamping Services

Hot stamping services

Our facility is equipped with hot stamping equipment to provide superior plastic decorating capability to make your product truly unique.

Hot stamping – sometimes called foil stamping - is a process where an engraved image or stamping die is heated and pressed against a part with foil between. Ink from the foil is left behind where the part meets to die. This is a dry, permanent type of marking, usually of a single color.

Most hot stamping is done on straight up-and-down presses – rest assured Plastocon is equipped with the equipment necessary to complete exactly what you need.

Sonic and vibration welding

Plastocon will help you complete your products in all designs to fulfill your part needs. Through joining components to adding inserts, etc. We have the equipment and know-how to get the job done.

We can custom fabricate & weld plastics of all different grades into any size or shape. Whether as part of a repair or new parts production, Plastocon has the resources to get the job done right.

Padprinting and silk screening

Plastocon's philosophy of providing value to our customers shows in the extras we do, such as machining valves or padprinting lock bodies.

For all plastic decorating Plastocon is your partner – including pad printing, silk screening & hot stamping.

Plastic Injection Mold Repair & Maintenance

Plastic injection mold repair and maintenance

Beyond new production, Plastocon is your partner for mold repair and maintenance. 

Sometimes full-scale reproduction is unnecessarily costly and doesn't provide enough of a return on investment to justify. Mold repair/maintenance keeps current working molds in functioning order and can save you money on new materials & bottom-up remolding costs.

Plastic Injection Molding Engineered Resins

Full range of engineered resins

From simple small geometry parts to large complex assemblies, Plastocon works in all thermoplastic resins (even ones other's don't) including PVC, CPVC, long fiber and liquid crystal polymers, PEEK, nylons, polyethylenes and propylenes. We have the specialized equipment necessary to successfully process virtually all engineered materials.

In addition we are always on the watch for new resins and processes which are introduced on a regular basis.
