In-house control
We have professional QC for control our mould quality and product quality.
The quality control process for rotational molding molds is a crucial step in ensuring that the rotational molding products meet the expected quality and performance standards. Here are some key aspects of the quality control process for rotational molding molds:
1. Incoming Material Inspection
Appearance and Dimension Inspection: Conduct routine inspections of the raw materials for appearance and dimensions to ensure they meet design requirements.
Performance Testing: Perform hardness tests and other performance evaluations to ensure the physical properties of the materials meet the standards.
Supplier Qualification Review: Only suppliers listed in the approved supplier directory can provide raw materials, and each batch must be accompanied by material certificates and heat treatment certificates.
2. Design and Development
Design Data Management: Ensure the completeness and consistency of product data, process data, and drawing documents, and establish a comprehensive file management computer database.
Design Validation: Validate the design through simulations and tests to ensure the mold design meets the requirements of the rotational molding process.
3. Manufacturing Process Control
Processing Inspection: Conduct routine inspections of the appearance and dimensions of CNC, EDM, and other machining processes to ensure processing accuracy.
Abnormality Handling: If dimensional abnormalities are detected, a three-dimensional confirmation can be requested; if overcutting, broken holes, or springing occur, a 'Quality Abnormality Notice' must be issued for review and resolution by relevant supervisors.
4. Assembly and Trial Molding
Assembly Inspection: Monitor the mold assembly process to ensure correct installation of all components.
Trial Molding Validation: Validate the mold's performance through trial molding to ensure the dimensions and appearance of the rotational molding products meet the requirements.
5. Finished Product Inspection
Appearance and Dimension Inspection: Conduct final inspections of the rotational molding products for appearance and dimensions to ensure they meet design requirements.
Performance Testing: Perform necessary performance tests such as strength and durability to ensure the usability of the products.
6. Factory Inspection
Comprehensive Inspection: Conduct a thorough inspection of the molds before shipment to ensure all indicators meet the standards.
Quality Certification: Provide quality certification documents to ensure customer trust in product quality.
7. After-Sales Service
Customer Feedback: Collect customer usage feedback and promptly address any issues encountered during use.
Continuous Improvement: Continuously improve the quality control process based on customer feedback and internal reviews to enhance product quality.
Through the above quality control process, the quality of rotational molding molds and their products can be effectively ensured, meeting customer needs.
