Explanation of quality control
Shandong Jinchi Heavy Industry Joint-Stock Co., Ltd. strictly controls each link of wear-resistant steel ball from steel plant selection, raw material purchase, steel inspection, quenching and tempering process control, finished product inspection, and strictly controls the performance index of steel ball according to the ISO9001:2015 quality management system certification procedure of the company, so as to ensure that the performance index of steel ball meets the technical requirements of the project and industry related requirements Technical specifications. Ensure the wear resistance, stability, maturity and reliability of steel ball.
Guarantee measures for raw material ordering
Our company has strategic cooperation agreements with well-known domestic state-owned enterprises, such as Laiwu branch of Shandong Iron and Steel Co., Ltd., Chengde Jianlong Special Steel Co., Ltd. and Huaigang Special Steel Co., Ltd. of Jiangsu shagang group. Each stage from material ordering to material inspection is reviewed and approved by technical experts, and finally determined by the technical director after being signed and confirmed by the relevant responsible person.
Production equipment performance assurance measures
All of them are produced with the most advanced and professional equipment, and cooperate with the process and quality inspection personnel to make the original records of various parameters in the production process, and operate and produce in strict accordance with the process requirements and specifications.
Process technology and quality inspection performance guarantee
Set up the project process specialist and quality inspector, set up the process in strict accordance with the parameters and indicators required by the contract and supervise the implementation of the process. The quality inspector shall track and record each parameter in the whole process.
Packaging and transportation performance guarantee
The packaging standard of the product is strictly in accordance with the international standards, to ensure that it can meet the lifting requirements for many times. Our company has established a strategic partnership system with several key shipping companies and logistics companies at home and abroad. We have transportation insurance for each vehicle, which greatly enhances our ability to resist risks.
