Injection Molding Company China | Cnmoulding LIMITED

Product Details: Plastic injection molding is a manufacturing process where thermoplastic pellets are melted and injected into a mold to form the desired part. The process involves feeding plastic granules into a hopper, melting them in a barrel with a reciprocating screw, and then injecting the molten plastic into a mold cavity. The mold is kept at a set temperature to allow the material to solidify, and then the part is ejected once cooled. Key components include the hopper, barrel, screw, heaters, nozzle, and the mold itself[2][4][5].

Frequently Asked Questions (FAQs)

What information do I need to provide to start the injection molding process in China

To start the injection molding process, you need to provide finished and checked 3D CAD files in formats like IGS (IGES) or parasolid. Additionally, you should supply the estimated quantities of the parts you need. With this information, the manufacturer can usually provide a quote within 48 hours.

How long does it take to produce an injection mold in China

The time to produce an injection mold in China varies based on the complexity, size, and material of the mold. For simple molds with no sliders and of small size, it can take around 1 month to 6 weeks. Larger molds with sliders can take up to 3 months. The design process itself for simple products typically takes about a week.

What are the key factors that affect the cost of injection molds in China

The cost of injection molds in China is influenced by several factors, including the complexity of the parts, part size, number of cavities in the tool, degree of automation, metal hardness, and required surface finish. Additionally, the type of material used and any markups by manufacturers or trading companies can impact the cost, which can range from $3,000 for small molds to $200,000 for complex ones.

How do Chinese injection molding companies ensure the quality of the parts produced

Chinese injection molding companies ensure the quality of the parts through various methods such as inspection, testing, and process control. They also maintain rigorous mold maintenance programs to ensure the molds are in good condition. This includes consistent preventive maintenance to meet design and functionality standards.

What secondary services can Chinese injection molding companies offer besides the primary manufacturing process

Besides the primary injection molding process, many Chinese companies offer secondary services such as assembly, branding (like logo printing and silk screen printing), general painting, chromating, and packaging (including blistering). They may also cooperate with freight forwarding companies to assist in shipping assembled or finished goods to your destination.
