HLT has established a complete quality assurance system and has passed ISO 9001:2015 quality system certification, ISO10012:2013 measurement system certification, ISO14001 environmental management system, ISO45001 occupational health and safety management system, GB/T29490-2013 intellectual property management system and CE certification for exporting to the European Union. The application of multiple systems ensures rule-based quality control and healthy development. HLT is the only mechanical equipment enterprise to win the Foshan Municipal Government Quality Awar
HLT has a number of advanced intelligent testing equipment and testing instruments both at home and abroad, such as API laser tracker, mobile direct reading spectrometer, static stress and strain test analysis system, ultrasonic flaw detector, coating thickness gauge, etc., which can meet the test verification requirements of product key performance indicators and reliability indicators to ensure product stability and reliability.
API Laser Tracker
AP| laser tracker is a key detection tool that uses laser interference ranging and angle measurement technology to achieve large component measurement and structural assembling. The APl laser tracker is equipped with a wireless tracking system and real-time error measurement function, its measurement radius is within 80 meters.The measurement accuracy is high, the resolution accuracy is 0,lum, and the measurement error is less than 0.005/1000.It is mainly used for process steps such as large-size components geometric tolerance measurement, structural parts assembling, and spatial error compensation of machine tools, such as tracking and key components measurement for front platen and cylinder crosshead,casing,dummy block,and frame.
Mobile Direct Reading Spectrum Analyzer
Hitachi mobile direct-reading spectrum analyzer is used for metal materials qualitative and quantitative analysis. lts characteristic is that various material grade data can be saved in advance, it can be judged whether the material meets the specifications by comparing real-time measurement results, greatlyimproving detection efficiency. lt is mainly used for testing the chemical composition of large and difficult-to-move parts, such as tie rod, front platen and crosshead, container and other key components.
Electronic Universal Testing Machine
Conduct mechanical performance tests on various metal materials,non-metal materials,composite materials polymer materials,etc.under conditions such as tension. compression, bending, shearing, peeling, tearing, short-term load holding,tension and compression cycles, etc. It is mainly used for tensile performance testing of bolts screws and other fasteners of extrusion press, and large casted and forged components such as tie rods, front and rear platen, container,extrusion stem, hydraulic cylinders moving crosshead, etc.
Tool Setter
The world's top tool setter, Zoller from Germany, is featured with "accuracy, reliability and convenience". Equipped with automatic tracking,automatic identification, and automatic measurement functions,it can realize fully automatic measurement of tools with extremely high accuracy. It is mainly used for pre-setting, measuring and testing for machining tools of compositing parts, so as to ensure the processing dimensions of the parts' key position, thereby improving the parts' quality.
Perfect Product Testing and Traceability System
HLT has established a comprehensive quality inspection and traceability system to achieve online management of product life cycles. Key components such as large-scale processing parts, electrical and hydraulic components, etc.; all carry unique "QR codes". By scanning the QR code of the workpiece, internal and external inspections are performed, and the key information such as the model, code, and number of the parts, manufacturing plant, purchasing information are recorded on the quality inspection work order at the handheld terminal, is automatically stored in the MES manufacturing execution management system to achieve "paperless inspection."
Through the MES system, product and component information can be queried, including press model, serial number, inspection personnel, inspection application and inspection date, etc.; to ensure the entire process quality control. The perfect product quality traceability system has greatly improved product quality control and strives to create "high-quality presses".
