Description:

Features of ALTURA 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 dustfree 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 

geometri 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 to 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.
