What is Annealing & Why is it Necessary

Plastic products are placed in a heated liquid medium or hot air circulation box at a constant temperature for a period of time, and then slowly cooled to room temperature, using heat to accelerate the relaxation of macromolecules in the plastic, thus eliminating or reducing the residual stresses in the products after molding.

Eliminate the local stress concentration phenomenon produced by different cooling speeds during the cooling and curing process of plastic products.

That's what the SUNLU FilaDryer E2 delivers
— a professional-grade 2-in-1 annealing and drying solution specifically designed for Engineering Materials.
