Our Post-Processing for Plastic Injection Molding

Our plastic injection molding services also include a range of Post-Processing to provide complete solutions for our customers. These operations include:

Surface Finishing

Surface finishing in plastic injection molding refers to the process of enhancing the appearance, texture, and durability of a plastic component by applying a variety of coatings or treatments to its surface. This can include techniques such as painting, plating, anodizing, and sandblasting, among others. Surface finishing is often used to improve the aesthetic appeal of a plastic part, as well as to provide protection against wear and tear, corrosion, and other forms of damage. At our plastic injection molding service, we offer a range of surface finishing options to meet the specific needs of each project.

Welding is a process of joining two or more pieces of metal or thermoplastic materials by heating their surfaces to the melting point and allowing them to cool and fuse together. In plastic injection molding, welding is often used to join two plastic parts together by melting the contact areas and bonding them together. There are different welding techniques such as hot plate welding, vibration welding, laser welding, and ultrasonic welding. The choice of welding method depends on the materials being welded, the design of the parts, and the required strength of the weld.



Assembly is an important Post-Processing in plastic injection molding that involves putting together multiple plastic components to create a finished product. Our team of experienced technicians can provide a variety of assembly services, including mechanical and ultrasonic welding, adhesive bonding, and snap-fitting. We have the capabilities to handle small or large-scale assembly projects, ensuring that your finished product meets your exact specifications and is ready for use.
