• Mold Cavity: 1
• Application: Automotive application
• Delivery: 100 days

Advantages of Large Injection Molded Parts

• Cost-efficiency at high volumes due to low unit cost
• High production rate suitable for mass production
• Design flexibility allowing complex geometries and tight tolerances
• Wide material and color options
• Consistent repeatability across production runs
• High level of automation to reduce manual intervention
• Good dimensional accuracy
• Acceptable surface finish compatible with downstream processes

Production method of Large Injection Molded Parts

• Samples / Drawing & Requirements: Review customer drawings and sample parts to define specifications.
• Mold Design: Collaborate with the customer to finalize mold structure and gating.
• Material Purchase: Procure appropriate steel and tooling components for the mold base.
• Mold Assembly: Assemble mold components with experienced technicians.
• Mold Inspection: Perform in-process inspections and quality checks.
• Mold Testing: Conduct trial runs, provide test reports with sample inspection results and injection parameters.
• Customer Confirmation: Obtain customer approval before full production.
• Finishing: Apply required surface treatments and finalize mold before packing.
