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.
