Finishing Options for Injection Molding
Choose from a wide selection of finishing options for molding that strengthen parts, improve cosmetic appearance, provide customization, and other benefits.
Mold texturing involves applying industry standard textures to a mold. With mold texturing you can expect the equivalent of a Mold-Tech finish.
Custom colorant matching is offered on customer-supplied Pantone numbers and customer-supplied part samples. The color matching process is simple and fast. Note that metallics, neons, and brighteners are not accepted at this time.
Threaded inserts are possible through secondary heat staking and ultrasonic welding processes. Heat staking is the process of heating threaded inserts and press fitting those inserts into molded part geometries. Keep in mind that we are unable to accept custom inserts at this time. Ultrasonic welding uses high frequency acoustic vibrations to press fit inserts into molded part geometries. Like heat staking, ultrasonic welding is currently open to threaded inserts, but not custom insert.
Pad printing transfers a two-dimensional image onto a three-dimensional object. We will print designed images like company logos on molded parts at Protolabs. All images are reviewed for size, color, and complexity restrictions, and images for printing should be provided with locations clearly marked in reference to part geometry. PM-TI and MT11010 are the most aggressive textures we can pad print.
Laser engraving is applied to the mold or directly to final parts for information such as logos or part numbers. Laser engraving ensures crisp, consistent information on each part or serialization. Acetal materials are not suitable for laser engraving.
Basic assembly at Protolabs includes fastening molded parts together that we’ve manufactured and/or applying of labels to individually bagged parts. We do not accept customer-supplied parts for assembly at this time.
