The product is processed through painting and printing processes, and a protective or decorative layer is applied to the surface of the product by applying specific coatings. Then print the pattern or text on the surface of the product through the concave convex changes of the printing plate.
1. Two Spindle automatic coating lines and four manual coating rooms can meet various production capacities.
2. Various reliability testing instruments are complete, and high temperature, high humidity, and surface strength are guaranteed according to customer requirements for quality assurance.
Mold forming is an important industrial production technology used to produce molded products, widely used in the compression molding or injection molding of plastics, rubber, ceramics and other products. Mold forming technology mainly includes various types such as injection molding, extrusion molding, and compression molding, each with its specific application scenarios and product characteristics.
■ Material: SUS/CU+NI+AU
■ Process: Material→Electroplating NI→Electroplating AU partially→Stamping
■ Advantages: changing the process in the past to lower electroplating cost and deter deformation.
■ Application: FPC contact brush.
■ Material: Aluminum
■ Process: Material→Bending→Blanking
■ Advantages: less process (< 10 processes) with progressive stamping, highly precision mold for bending, strokes per minute 80, 50% less than the cost of die-casting.
■ Application: heat dissipation for mini 3C products.
■ Material: Aluminum
■ Process: Material→Bending→Blanking
■ Advantages: with progressive die and precision bending technology, hole alignment through bending process many times.
■ Application: battery box gnd holder.
■ Material: SUS
■ Process: Material→Bending→Blanking
■ Advantages: bending angle of 36mm height will be less than 0.2 degree after the material is bent many times.
