Pad Printing

Pad printing is a process which colored inks are stamped onto a plastic part. A steel template in the shape of the desired design or text is created and acts as an ink reservoir. The ink is then transferred to the part using a flexible pad. Multiple colors and artwork are possible

Laser Engraving

EuroPlast’s laser engraving machine is capable of highly detailed, permanent engraving on metal or plastic. Laser markings will not chip, peel, smear or wash away and are not affected by humidity or other environmental conditions.

Sonic Welding

Sonic Welding Services

Sonic Welding Services

Sonic welding is a process in which a non-stationary part is vibrated against a stationary part at a high frequency. The friction created at the contact points effectively melts the parts at those points and welds them together. Through the process, the two parts are welded into a single part which cannot be disassembled.

Sonic welding normally is used when both parts are comprised of similar materials, however, metal inserts can be sonic welded into a part by vibrating the insert and forcing the surrounding plastic to melt and secure it.

Hot Plate Welding

Hot plate welding is used to weld two parts that are larger than would be practical for sonic welding. The parts are seated in custom fitted nests and a hot plate centered between them heats the contact points. The plate is then removed and the two parts are pressed together to form one complete part.

Heat Staking

EuroPlast Can Assemble Parts and insert Items into Plastic Injection Molded Parts.

EuroPlast can assemble parts and insert items into plastic molded parts.

Heat staking is a process of mechanically bonding two parts together which are comprised of dissimilar materials. This process can bond plastics with greatly differing melt points, or two completely different materials, such as metal and plastic.


Assembly can range from manually snapping two parts together to customized complex insertion procedures. For one customer, EuroPlast designed and manufactured pneumatic assembly devices and fixtures to insert a small integrated circuit board into a molded part.
