Precision-Driven Mold Quality Control: Ensuring Excellence at Every Stage

At TONGDA LINK, we ensure mold quality control through a combination of rigorous processes, precision equipment, and expert oversight.

Multiple Quality Checks:

  • Throughout the manufacturing process, we implement stringent quality checks at every stage:
    • Incoming Material Inspection: Materials are checked for their specifications and quality before use.
    • In-Process Inspection: At each critical phase of mold manufacturing, dimensional and visual inspections are conducted to ensure the product is meeting design specifications.
    • Post-Production Testing: Completed molds undergo thorough testing, including trial runs, to verify their performance under real production conditions.

During the injection molding production process at TONGDA LINK, quality control is essential to ensuring that the molded parts meet the required specifications and standards.

In-Process Inspection

  • Dimensional Checks: Parts are checked periodically for critical dimensions using precision measuring tools such as calipers, micrometers, and coordinate measuring machines (CMM).
  • Visual Inspection: Operators regularly inspect parts for visual defects such as flash, sink marks, warping, short shots, and surface finish irregularities.
  • Sampling Plan: Following a pre-established sampling plan, samples are taken at defined intervals during production and tested to ensure consistency in quality.
Our engineering team, which includes 3 mold designers and 2 project engineers, meticulously designs each mold to meet specific customer requirements. Using advanced CAD software, we ensure that all design specifications are accurate and optimized for functionality.

Precision Engineering and Design

Our 10 CNC machines, capable of machining with a precision of up to 0.002mm, allow us to produce molds with extreme accuracy. This precision ensures that each mold performs reliably and consistently during production.

High-Precision CNC Machining

We use high-quality steel and other materials sourced from trusted suppliers, ensuring the durability and longevity of our molds. By selecting appropriate materials based on the production needs, we reduce the risk of wear or deformation during use.

Material Selection

Throughout the manufacturing process, we implement stringent quality checks at every stage of mold manufacturing.
