Description:

 

Features of NICE high-precision adjusting shims:

1. Product precision

Precision is the key requirement for adjusting shims.Accurate adjustment for fuel quantity si completed depending

 on grouping of products.We adopt high-precision optical ruler to control lapping dimension,and can control product

 precision dimension within 0.002mm.We finish grouping by inspecting one product with two products inside 

dust-free workshop.One product is measured for no less than 5 times from finishing process to finished product.(Testing methods:use high-precision digital display micrometer to measure conformity between actual dimension 

and required dimension,and whether the dimension for same-grouped products is same or not.)

2. Geometric tolerance

Geometric tolerance of adjusting shims is directly related to the maintenance quality of fuel injectors.Main geometric

 tolerance requirement for adjusting shims is depth of parallelism.Large shim will affect product tightness while 

small shim will affect reliability and stability of products.We adopt high-precision double-sided lapping machine to

 ensure and control depth of parallelism for products within 0.002mm.Adoption of one-time forming process better

 ensures product axiality.(Testing methods:use parallelism tester and deflection instrument t test parallelism depth

 and axiality respectively)                                              

3. Material quality and hardness

Material quality and hardness of adjusting shims affect durability and stability of products.We choose high quality 

material and advanced thermal treatment equipments/technology.                   

 

4. Cleanliness                                                                             

 

Product cleanliness can be better ensured due to multi-channel ultrasonic cleaning, dust-free workshop

 packaging and plastic case sealed packaging.

 

 

WUXI ADM TECHNOLOGY DEVELOPMENT CO.,LTD is mainly engaged in diesel nozzle, plunger, delivery valve

 and other precision matching parts production and sales, as well as the general import and export trade.

We have advanced equipments and technique, full testing machines, very strong technical capabilities. And we
