::Nano mould release successful application
Project:
Military
Usage:
M16, 5.56 rounds
Plastic Bullet Blanks
Material: 66% glass filled
Mold
material: STAVAX
|
Problems: Customer
molding plastic bullet blanks in a 32 cavity mold, using special
formulated resins with 66% glass filled content material.
The inserts were Titanium coated to improve the wear resistance caused
by the abrasiveness from the resin.
But despite to the preventive measures, it still didn't last long after
40-50K cycles where the coating starts to chip and flake.
Huge rejects of deformed and bulging parts around the profile area.
In worst scenario, the whole mold is required to be stripped down in
order to abstract the stuck parts.

Before using Nanomouldrelease
coating
Reject rate are running very high at 6-7% with
the aid of mold release agents every 4-5 cycles. Expensive titanium
coating inserts are required to monitor closely for chipping,
and extra new inserts are fabricated to replace worn out ones due to
tight dimensional integrity. Only 2 million pieces are produce in a
month.
After
coating with
Nanomouldrelease,
Customer achieved
uninterrupted molding of 50,000 cycles = 1.5 million pieces within 2
weeks without any aid of mold release agents. Huge saving are recovered
as overall reject were down to 0.4 percent.
Fewer inserts are made due to regular mandatory maintenance every 2
weeks.
The company profited instead of losing money in this project.
