Shenzhen Jiarun Precision Science&Technology Co. Ltd
Brief introduction:

Shenzhen Jiarun Precision Science&Technology Co., Ltd, which was establish in 1997, is located in Shenzhen, China. the total investment of company over 40 million RMB, with annual production is RMB 30 million, there are 125 employees, 70 of which are professional operetors, and 15 professional engineer, we are on of largest and most professional manufacturer of motor stator rotor lamination progressive stamping mould.

The company focus on  motor stator rotor stamping mould. We import the motor stator rotor stamping mould technology from Japanese Mitsui high-tech company and we also import advanced technology from Japan, Germany. Now we have become the NO.1 manufacturer in South of China. we also cooperate with Midea, Casic, Canon, Tong-chang electric machinery, Chigo Air conditioning, Mitsubishi Electric, Mitsui High-Tec etc, we offer them motor core stamping mould, and they also give us some suggest about the die. mow our mould have export to Europ, America, Japan etc and we also obtained good reputation in the oversea market.

The company processes many precise equipment, such as Sodic EDM machine (12 sets ), Taiwan grinding machine (15 sets ), big milliong machine (3sets ), Taiwan CNC center machine (4 sets ), CNC milling machine (15 sets ), press machine from 25T to 400T (20sets ). Greman 3D-CMM universal microscope machine, Taiwan projector, etc.

The company specialzing in progressive lamination stamping die for various motor core used in home appliance, automobile, transfer and so on, and we also product stamping spare part, such as punches, inserts etc, all the die are designed by senor engneers. and we can ensure their high precision, long life, and good stability.

There are 35 professional engineers and opereatios at JR. who engage in technical research and development, by advanced software, we improve our design and calculation, which facilitates desigan and therefore shorten lead time, all motor stator rotor core progressive stamping dies are designed by senior engineers to guarantee their high precision ,long life, and great stability.

Motor lamination progressive stamping mould
JR motor core die: product series of progressive die, various laminations and cores for motors which involve air-condition compressor motor, refrigerator motor, plastic sealing motor, automobile motor, generatoe motor, stepping and servo motor, universal motor, shaded pole motor, dc motor.
 
JR mould capacity: we are make progressive stamping dies for lamination from 3mm to 2000mm, the maximum die that we have made is for 700mm stator rotor lamination, meanwhile, we are capable of functions like interlocking, skewing, shoulder holes for laminations from 5mm to 300mm, and rotation for laminations within 180m.

Spare part: we use wire EDM and grinders to process key parts in the die, and their machining precision is within 0.005mm, while roughness between Ra 0.05 and Ra0.4, on the other hands,we continuously work to improve the standardization, so that we can meet your requirements quickly with high quality. interlock and counter punch, slot punch, pilot punch, punch and die for weld notch, ejection pin and kicher, interlock and counter cut die, slot cut die, pilot cut die, feed error protector, pilot pin, location pin, round pin, round lifer, notched round lifer.

The level of standardization and coverage rate of standard parts here in JR ranks among the best in this industry, we use alloy steel of high intensity, high speed steel or carbide materials for main mould parts likes upper plate, lower plate, spring -loaded strippers, and carbie parts, on the other hands, we not only introduce in auto feeding device and feeding error protector, but also precisely machining relevant holes in stripper plates, so that we can guarantee dimensions and relative locations for good mould intensity and long time.
