Blasdel Plastic Annealing Oven

Blasdel Enterprises recently designed and built an oven for annealing plastic on interior door parts to hold dimensional tolerances.  After extensive testing utilizing medium wave infrared and high volume air, it was determined in our test facility that the high volume air oven returned the best results.  The part was difficult because there were multiple types of material that reacted with heat at temperatures.  When testing in the infrared oven, some areas melted and other areas did not reach the 200 degrees F that was needed to maintain the tolerances.  Utilizing our high volume air oven test set, we held the part at the necessary temperature with very little fluctuation in part temperature.

Even air flow within the oven is recirculated to reduce heat loss thereby adding to the energy efficiency of the plastic annealing oven and conveyor system. The plastic annealing oven is built with an integrated conveyor added which automates the process.  Design and construction of the conveyor has been modified to align with the customer’s current conveyor system.  Access doors allow for maintenance of the oven and to access parts, if necessary.  The control panel is mounted on the oven.  This one piece design allows for easy installation for the customer.

The success of this oven has led the customer to work with Blasdel to add more of our equipment to their facility for other processes.  Testing will be in our facility to determine the best infrared and/or air recirculation process for their parts.
