Technical Advice

1. To help avoid sink marks (depressions) in the plastic mouldings and make them easier to manufacture, keep wall thickness' even and avoid thick areas by coring them out. As a guide, joining walls should be 50% of the thickness of the thickest section.

2. If possible, state generic plastic material types on drawings e.g. 10% Glass Filled Polycarbonate rather than trade names e.g. Lexan 500R - if you prefer, please state e.g. Lexan 500R or equivalent. Also, try to specify a plastic material that adequately deals with your needs, rather than one that greatly exceeds them.

This enables us to purchase the moulding material you need from more than one manufacturer and thus, keep lead times to a minimum and save you money by keeping our plastic moulding prices to you at the same level for longer. For help with choosing plastic materials, please view our plastic material guide.

3. Consider the environment that the plastic mouldings are going to be used in - will they need to have e.g. a certain mechanical strength, be clearly colour coded or protected from ultraviolet light or static damage?

If so, ensure you state these requirements when asking for a plastic moulding quotation - without them, incorrect plastic materials could be suggested, inaccurate quotations given and even costly tool modifications incurred.
