Value Added Process
CLS is your best choice for an all-inclusive custom injection molding operation. By incorporating our value-add services into the molding process, we ensure deadlines are met and your product is ready for the end users.We strive to help our customers achieve a greater ROI on their custom injection-molded products. Some of our value-added services include:
High Frequency Welding
High frequency welder processing is a heat treatment process that uses a machine known as a “high-frequency welder”.

High frequency plastic welding machine can process the following materials, PVC, EVA, PEVA, PET, APET, PETG (GPET), GAG, TPU, TPR, PU, PE, MPE ... etc. thermoplastics, the material containing the above products include fitting, coating fabrics of these materials, textile and synthetic leather materials and and foaming materials such as PU foam PVC can be used to process on high-frequency machine.

We believe most of injection molding fatory has ultrasonic welding, but they don`t provide this kind of service. It`s proud to say: CLS can do it.
Riveting Service
We do riveting and assembly in our plant. We provide the equipment and trained personelle, you just send us your components and we will return to you completed assemblies. From short runs of just a few hundred pieces to long runs of many thousands we can assemble, rivet and package your parts.
Pad Printing
Two Color Sealed Ink Cup Pad Printing-Pad Printing Logos, Labels, Buttons, etc.Pad printing is the process of printing ink onto plastic parts. Often plastic parts have irregular shapes and contoured surfaces that make it impossible to print directly onto them. With pad printing, a silicon pad is pressed onto a laser etched ‘inked surface’, then transfers the ink onto the plastic part by simply pressing down onto it.
Ultrasonic Welding
At CLS, we ultrasonically weld parts together to create bonded thermoplastic units that enclose the complex inner-workings of business machines, medical devices and other types of equipment.

Our ultrasonic welding process produces finished components that pass performance tests for gas-tightness, air-tightness and water-tightness when specified. Product testing is documented and traceable by lot when required.

Looking for a clean, fast and highly automated process for medical, business and other technical equipment? Call us to learn more about the advantages of bonding materials with high-frequency ultrasonic vibrations — no bolts, no nails and no adhesives.
Screen Printing
If your products was produced with screen printing necessary, we could provide that in house.

All kinds of plastic PET, HDPE, PVC, LDPE, PP, PS...etc, bakelite plastic screen printing Various product container screen printing, screen printing, cosmetics, electronic products, screen printing, screen printing daily necessities, auto parts Screen Printing Also provide a small screen printing production in response to the required development of new products, as well as the screen printing Advisory
