The introduction of precision and high-performance moulds has led to ever-increasing demands on mould manufacturers in recent years. Since the precision of the shape is determined by the dimensional accuracy of the electrode, it is essential to carry out accurate measurements of the size and shape of the electrode before processing the shape.

Changyuan Technology (Tianjin) Co. Ltd (CHYUAN) specialises in the development and manufacture of automotive injection moulds. With a planned production capacity of 450 million moulds, the company aims to develop into one of the largest single manufacturers of automotive injection moulds in northern China.
For increased efficient production of precision moulds, CHYUAN has commissioned an automated production line for electrodes and mould inserts, which enables the integration of electrode disassembly, processing, inspection, repair and offline processes. Since the measuring system used is the key to quality assurance, CHYUAN prefers the use of coordinate measuring machines (CMMs).
A CMM provides one of the most effective solutions for measuring and collecting dimension data. First, it can replace a variety of surface-to-surface measurement tools and expensive combined gauges. Secondly, the CMM can reduce the time required for complex measurements from hours to minutes. Thirdly, it guarantees both the efficiency and accuracy of measurement of size, shape and positional tolerance of the electrode.
Automated Measurements in the Direct Production Environment
CHYUAN relies on the WENZEL coordinate measuring devices XOrbit77 and LHF 2517. The figures represent the measuring volume in the X and Z axes of 700 mm x 700 mm and 2500 mm x 1700 mm, respectively. The XOrbit was seamlessly integrated into the production line for electrodes and mould inserts for automated 3D coordinate measurement in 2019. The CNC measuring device is ideally suited for the shopfloor environment and can be equipped with switching measuring and optical sensors. The XOrbit offers excellent value for money with high mechanical precision and low operating costs.
Meanwhile, the LHF 2517 is a large measuring instrument in gantry and bridge construction for medium and large workpieces. The floor-level design of the LHF allows easy assembly with large parts with high freedom of movement for the user. The double drive in the Y-axis of the LHF ensures high measuring speeds and excellent stability of the guides.
