Before entering production, all raw materials (such as steel from brands like DAIDO, HITACHI, and ASSAB) undergo multi-dimensional rigorous inspection: verifying material certificates, testing physical properties (hardness, toughness), and screening for appearance defects (cracks, impurities). Only materials that meet ISO standards and customer-specific requirements are allowed to be stored in the warehouse. This eliminates material risks at the source, ensures the durability of subsequent molds and components, and prevents cost losses and delivery delays caused by material issues.

It covers the entire process of mold manufacturing and injection molding: during the mold processing stage, after machining with Makino CNC equipment, precision verification (±0.001mm) is conducted using JOINT grinding machines, and dimensional inspection is performed with Sodick Wire Electrical Discharge Machining (WEDM); during injection production, parameters such as temperature and pressure are monitored in real-time, and component dimensions (via Mitutoyo Coordinate Measuring Machine) and surface roughness (Ra 0.04μm standard) are sampled and inspected every 2 hours. Inspection data is recorded throughout the process to ensure each step meets design specifications and avoids batch defects.

When starting mold trial or injection production for each batch, the first article is produced first for full-item inspection: verifying 3D drawing dimensions, validating assembly compatibility (e.g., the fit between automotive components and vehicle interfaces), and testing functional performance (e.g., the sealing of medical components). Mass production can only begin if the first article is qualified. If deviations are found (such as dimensional out-of-tolerance or appearance defects), Mold-Flow analysis is used immediately to optimize the process, ensuring mass-produced products are fully consistent with design standards.

100% full inspection is conducted before products leave the factory: for molds, inspecting cavity finish, mold clamping clearance, and the flexibility of the ejection system; for injection-molded components, checking dimensional tolerance (within ±0.002mm), appearance (no bubbles, scratches), and packaging integrity (moisture-proof, anti-collision). All inspection data is entered into the system for archiving, and an inspection report is delivered with the goods, ensuring every set of molds and every batch of components received by the customer meets the "zero-defect" standard.

A 24-hour response mechanism is established: after a customer reports an issue, a dedicated engineer is assigned within 1 hour, and a problem analysis report (such as the cause of dimensional deviation, traceability of appearance defects) is issued within 24 hours; a solution (such as free re-production, on-site debugging) is provided within 48 hours, and the effectiveness of rectification is tracked. At the same time, the issue is included in the "quality improvement database" to optimize subsequent production processes (such as upgrading inspection standards, adjusting raw material screening items), achieving "one problem, permanent avoidance" and safeguarding the long-term interests of customers.
