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 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.
