Common burr treatment method
Common burr treatment method for silicone rubber products
1.Deburring by hand
Manual trimming is a traditional trimming method，It debur by punch die cutting
and scissors and a scraper.Manual operation may lead to differences in product quality and speed,
so it is necessary to make clear the product parts and technical requirements before deburring,
they should master the correct deburring methods and konw how to use the tools correctly.
At the same time, the proficiency of the operator is relatively high.
In the production of rubber miscellaneous parts, most of the trimming operation is manual
operation in different forms.This operation will make the production efficiency is low, the production cost is high;
2.Mechanical trimming
The main products are punching, grinding wheel edging and circular knife edging,
which is suitable for specific products with low precision requirements
1)Mechanical cutting trimming with pressure machinery and punching die, punching knife, remove the burr
2)Mechanical cutting trimming is suitable for trimming larger shape products with the cutting tools
3)Mechanical grinding and trimming is suitable for die rubber products with inner hole and outer circle,
but the precision of grinding and trimming is low
3.Nitrogen freeze trimming
Special frozen trimming machine equipment, it's using of liquid nitrogen (LN2) to make
the finished raw edge brittle at low temperature, use specific frozen particles (projectiles) to
hit the raw edge, in order to quickly remove the raw edge
4.Flyless moulds
Adopting the flange-free die in production, the trimming work becomes simple and easy.
The flange-free mold forming method can completely omit the trimming process,
improve the product quality and performance, reduce labor intensity and production cost
and other characteristics, and has broad prospects for development
