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 180mm

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.

 Daily inspection

1). The inspection of the product 
The product quality is up to the die production and assembly procedure. The user could find out the die performance through the inspection of the product: Dose it needs some adjustment? Is there any problem with the die? The inspection of the product contains as least the following points: 
 1.Is the dimension of the product in accordance with the drawing, if it is out-of-tolerance, the cutting edge needed regrinding.
2.Check the surface and the shape of the product.
3.Check the burr of the product 

2).The inspection of the die performance
 Aside from the inspection of the product, the day-to-day inspection of the die is also required. As follows: 
 1.Check the surface of the punch and matrix:, make sure there is no fissure and crack. Keep the cutting edge sharp.
 2.Check the each working parts , to make sure the normal performance and coordination of each parts.
 3.Check the guide assembly; to make sure there is no wear-out and roughness in some place; keep the guide bush, guide post and the rolling ball are in good coordination.
  4.Check the precision of the standard parts, the function of the stripper plate and the elasticity of the spring parts.
5.Check the locating assembly, to keep the firmness of the fastener,such as bolt.
 6.Check all the attachments and the protective assembly, to make sure they are in good state.

3).Maintenance and daily upkeep
 The multiple positions hard alloy progressive die is special technical equipment, which is marked by high precision, high speed and long life-term. The Maintenance and daily upkeep are important for the normal performance of the die. Proper and regular maintenance could longer the life-span of the die and improve the quality of the product. The following points are essential:
1.First, make sure the die and the press is well-matched.
 2.Do the Try –stamping according to the adjustment and operation procedure. Check the strip layout and Dimension Precision such as the height of interlocking point of stack. 
3.Comply with the operation procedure; oil the each working parts and matching surface.
4.Apply the rust-proof oil after cleaning; cover the upper guide bush hole with a piece of paper, to prevent the dust and other article drop into the hole, other wise the precision of the die may be affect. At last, deliver the die to the appointed place in time.
5.When the die is put in storage, check carefully and take a record of the important information, such as die code , name, time of storage, stamping times, repairs times, repair info and etc. The last strip layout should also be kept with the die.
  6.The storage room should be well-ventilated and fireproof. A person is needed to take charge of it.
7.The regular maintenance and change of the following parts are needed:
