Plastic Annealing Oven

Plastic Annealing Oven: Delivering Finished Plastic Accessories for Powerful Industry Applications!

MV International manufactures and distributes plastic annealing ovens with different styles and functions. We resort to the process of annealing for heating plastic parts at a specific temperature to turn in soft and free-flowing besides shaping it with the help of mold and cooling it. The plastic loses stress under the annealing process and becomes an improved product to match all strong industry applications.

The annealing process that we follow is ideal for increasing the stability of dimensions, improving electrical or mechanical properties and enhancing the capacity of machining. The plastic annealing oven can only be used for heating plastic. Induction of the residual stresses is possible while machining the plastic parts. Such stresses can curb cracking and wear resistance besides affecting the strength of the material.

This is when the plastic annealing oven comes into play; it helps in heating plastic parts as per requirement. The transition temperature has to be checked since the plastics must receive annealing heats below this temperature. It’s necessary to continue such heating for a preset time frame.
