During machining, areas of localised stress develop.  In acrylic, this frequently leads to the emergence of crazing which has a detrimental effect on the appearance of the component.  Even if crazing does not form, the localised stresses can lessen the durability of a part.  We will advise you as to whether or not your component will benefit from heat treatment to avoid these problems.  Annealing or normalising will be recommended for the benefit of your acrylic component, with the procedure being carried out in-house.

Other plastics can also benefit from annealing and this will be advised where appropriate.
