Company Profile 

Jiarun precision mould (shenzhen) co., LTD., founded in 1997.Specialized in all kinds of motor iron core design research and development, mold manufacturing, stamping products production and sales for the integration of enterprises. Locating in shenzhen songgang YanChuan north industrial park, liaocheng foot forest farm, 20 km away from shenzhen airport, and high-speed songgang export 5 km, from dragon, is apart from the 107 national highway 3 kilometers, the transportation is convenient. We have been to uphold the nuanced, and high quality products and services, for customers to provide quality assurance, guarantee product quality.

Our management to the quality  is mainly manifested in the following aspects:
1.Company culture of quality management, through the employee training training quality consciousness .International quality certification.
Quality certification management, through quality system certification agency for our products and services for the actual assessment, audit and certification.
2. standardization of testing machines and tools equipment, for each test equipment and tools maintenance team on a regular basis, prevent errors in time, guarantee the accuracy of the equipment to normal operation and measurement results.
3.there are strict process and link to ensure quality, keep the test records, to be back late.
4. the test and the result report of the sample.
5.The requirements to supplier's regular audit, strict and procedural.
6.Mould process smooth and effective communication between various departments, timely reflect the problems, solve the problem.
7.The specialist is responsible for the project management, and the execution of project progress and implementation are in good condition for truthfully feedback on a regular basis.
8. the standard QC file to guide, make some reference to the quality of work, more smooth and disciplined.

Process performance:

1. Have relatively low hot forging deformation resistance, good plasticity, forging temperature range wide, cold forging crack crack and precipitation carbide network tend to be low.
2. Wide temperature range and spheroidizing annealing annealing hardness is low and the fluctuation range is small, spheroidization rate is high.
3. Low cutting parameter, cutting tool wear and tear, lower surface roughness.
4. When heated to high temperature oxidation resistance with good, decarbonization speed slow, is not sensitive to the heating medium, produce pitting tend to be small.
5. A uniform and high surface hardness after quenching.
6. After quenching can get deeper hardening layer, the ease of quenching medium can be hardened.
7.Conventional quenching small volume change, shape warping, distortion mild, abnormal deformation tend to be low.Conventional quenching cracking sensitivity is low, is not sensitive to quenching temperature and shape of the workpiece.
8. Limit dosage of grinding wheel relatively low loss, no burns, insensitive to the quality of grinding wheel and cooling conditions, are less grinding and grinding cracks.

We mainly produce:

1. hardware stamping/punch/progressive/transfer/compound/high-speed dies for: motor lamination core, stator and rotor motor lamination, capacitor motor, shaded pole motor, pump motor, brushless motor, universal motor, servo motor, vehicle motor etc.

2. various metal stamping/punch parts which are laminated/punched/stamped by our toolings.(rotor and stator motor lamination and mold for them are leading products of J.R.)
