⚠️ WARNING ⚠️
Choking Hazard – Small Parts for most items on this site.
Not for children under 3 years old.
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 FilaDryer E2 delivers — a professional-grade 2-in-1 annealing and drying solution specifically designed for Engineering Materials.
How to Anneal?
- Select the Temperature: Determine the right temperature based on the material.
- Control Heating Rate: Ensure the part is evenly heated.
- Maintain a Constant Temperature: Adjust the duration according to the size and material.
- Manage Cooling: Allow for gradual cooling or use controlled cooling for the best results.
Tips for Successful Annealing!
- Precise temperature control is essential to avoid overheating.
- Test with small models first to reduce trial-and-error costs.
- Allow for shrinkage, and adjust your design accordingly.
No More Worries about Safety?
Intelligent protection system, an alarm beep will sound if the temperature exceeds the preset value by 10°C or the machine continues to work improperly.
