Quality & Service

We use high-hardness gray iron to make molds, and use high-precision machining centers to process molds, which can ensure that the accuracy error of the product is 0.5MM, and the mold can be used more than 100,000 times. Suitable for making products with high precision and small weight.

The molding machine is used to spray 200 mesh sand into the mold to make the sand shell for casting, which needs to be kept warm for 7-12 hours after casting.

Advantages: The rough castings have high precision, small machining allowance, and can be mass-produced quickly.

Disadvantage: The molds are expensive and are not suitable for large-scale castings or small-batch castings.

Quality Control

A Commitment to Quality, Validated by Data

Our ISO 9001:2015 certified quality management system governs every stage of production, from raw material verification to final dimensional inspection, ensuring your components meet the most stringent specifications.

Raw Material & Melt Analysis

We begin with rigorous testing of all raw materials. Our Spectrum Analyzer verifies chemical composition before melting, while our CET intelligent tester ensures optimal molten iron properties. 

In-Process Metallurgical Control

Throughout the process, we conduct metallographic detection to confirm microstructure, hardness testing, and tensile strength tests to validate mechanical properties against your requirements. 

Final Casting Integrity & Precision

Every casting undergoes final inspection. We utilize Ultrasonic Flaw Detectors to guarantee internal soundness and 3D Scanners to verify dimensional accuracy down to the micron level.
