Trimming
What is Metal Trimming Process & Die Cutting & -
Trimming Services
Trimming is the act of removing flash or burrs on the edge
of the workpiece.Remove flash or burrs from rubber molded
parts, plastic molded parts, metal castings, or the edges of
workpieces.This process is an important process to ensure
the size of automobile covering parts.The determination of
the trimming line is the key to this process.
Minghe has an advanced trimming machine that uses the
low-temperature freezing effect of liquid nitrogen to
embrittle products made of rubber, plastic or
zinc-magnesium-aluminum alloys. High-speed injection of
polymer particles hits the product burrs to remove burrs
with high efficiency and precision.
Minghe's die cutting and trimming services were originally
added to compliment and support our forming capabilities.
Today, customers utilize our industry leading trimming
services even when forming is not needed. For 35 years, we
have been evolving our trimming services to provide
customers with the right solutions to their specific
application. Minghe engineers will review the product
specifications, material call outs and volume requirements
to select the most cost effective solution for your trimming
project.
Benefits of Metal Trimming Process
The functions of metal trimming can be summarized as
follows:
-
– Simple operation: ordinary workers can operate the
machine proficiently after half an hour of training,
and there is an advanced automatic control system to
prevent workers from misoperation.
-
– High production efficiency: the average daily
processing volume of a frozen trimming machine is
equivalent to the trimming workload of 50-80 skilled
workers.
-
– High precision of trimming: it can remove very small
and hidden flash, not limited by the shape of the
product, with high pass rate and stable trimming
quality.
-
– It can remove the flash from small rubber and
plastic products of any shape, brittle plastic
products and magnesium alloy, zinc alloy, and aluminum
alloy castings with complex structure.
-
– Do not damage the surface of the product, improve
the appearance quality of the product, and increase
the service life of the product.
-
– It occupies a small area, only 4~10 square meters
for a frozen trimming machine plus auxiliary
equipment.
-
– Reduce the cost of mold use and rubber material. The
equipment does not need torn edges. It only requires
the flash to be as thin as 0.2mm or less, the overflow
groove is as small as possible, and the flash margin
is only 1/5 of the tearing die -1/10.
-
– Energy saving and environmental protection: The
machine consumes extremely low energy and discharges
other original components of nitrogen.

Choose the Best Trimming Process
After browsing a list of Surface Treatment services, select
a process based on essential considerations, like production
time, cost-effectiveness, part tolerance, durability and
applications. High-tolerance CNC milling, turning parts are
not recommended to apply secondary metal surface finish,
because the treatment may change the sizes of the finished
part through removing or adding a small amount of materials.
