Automatic deburring is a process for removing flash from molded rubber parts. We use liquid nitrogen, high - speed rotation and shot blasted plastic media in varying combinations to remove the flash in a highly precise, economical and expedient manner. Parts that have thin flash can be quickly and thoroughly cryogenically deflashed. This process is exceptionally good at removing the inner dimensional and complex flash that cannot be removed by any other method.
Application
O - rings, gaskets and other rubber sealings
Insulators and other electric / electronic components
Valve stems, washers and fittings
Short tubes and flexible boots
Rubber absorbers and bumpers for automobile
Face masks & goggles
Mobile phone housing and intelligent watch strap
Zinc and mag alloys like door lockers for auto cars

Plasticizer A LTS-82A 86A is a mixture of high molecular weight aliphatic polymers containing unsaturated bonds and active agents.
The product does not affect the physical properties of the rubber compound, and has the property of reducing the Mooney viscosity and shortening the mixing time, and the hardness of the finished product is not affected.
Inorganic fillers such as carbon black and white carbon have high-performance dispersion, improve extrusion and injection properties of rubber compounds, smooth surface, and significantly reduce internal porosity.
This product can reduce the heat generation of the rubber compound, reduce wear, improve tire life and reduce energy consumption.
