Annealing Plastics
Annealing is the process of heating plastic to a temperature where it softens enough to flow freely. From here, it is in molds to take shapes where it will later slowly cool. This process helps to reduce the stress on the plastic, creating products that have a better finish. Memmert annealing ovens can range in size from 32 to 1060 liters in volume. The maximum temperature attainable in these ovens is 300C/572F.
Memmert annealing ovens for plastics come in stainless steel, which is scratch-resistant, hygienic, and robust for an ever-lasting design. The annealing oven from Memmert also comes with adjustable parameters such as temperature (Celsius and Fahrenheit), air flap position, program time, time zones and daylight savings time. The timer is a digital backward counter that has a target time setting, which is adjustable from 1 minute to 99 days.
