1. Design and mold preparation

Design phase: Determine the final design plan based on customer needs or product usage. When designing, factors such as material properties, structural strength, and subsequent processing requirements need to be considered.

Mold development: Produce molds based on design schemes. This process includes steps such as CAD/CAM design and CNC machining to ensure the accuracy and durability of the mold. High quality molds are the foundation for ensuring product quality.

2. Material selection and pretreatment

Material selection: Zinc alloys with good fluidity and casting properties are commonly used. Depending on the specific application requirements, zinc alloys with different proportions may be selected.

Smelting: Place the selected zinc alloy in a dedicated furnace and heat it to a liquid state, and remove gas impurities through degassing treatment to reduce defects in the finished product.

3. Die casting molding

Injection molding: Install the preheated mold onto the die-casting machine, and then quickly inject the processed metal liquid into the mold cavity.

Cooling solidification: As the temperature decreases, the metal liquid will gradually solidify and form. Controlling the cooling rate during this process is crucial to prevent the formation of cracks.

Demoulding and removal: After the product has completely cooled down, open the mold and remove the casting from the mold. At this point, the obtained blank is unprocessed.

4. Follow up processing

Deburring: Removing excess material or irregular parts from the edges.

Surface treatment: Polishing, painting, electroplating and other operations are carried out as needed to improve appearance quality or increase corrosion resistance.

Packaging inspection: Finally, conduct a comprehensive inspection of the finished product to ensure that it meets the specifications and is properly packaged for transportation and storage.

5. Quality control

Strict quality control measures are required throughout the entire production process, including raw material testing, inter process inspections, and final product testing, to ensure that each batch of products meets consistent standards.
