Whether the requirement is for a new part, or replacements for existing parts that do not meet your expectation in quality, cost, performance or availability, the same set of general rules apply. Good communication is vital if parts are to be supplied to customer satisfaction at the right price. An existing sample or basic drawing is a good start, but questions answered now will prevent surprises and difficulties later.


We strongly recommend that a specification is produced to consider and record the following points:

• Is it a new part or potential replacement of existing part?
• What is the expected usage - either batch or annually?
• Are there price constraints on parts or tooling?
• How is the component to be used?
• Will there be movement, vibration or compression?
• What is the highest service temperature?
• What is the continuous service temperature?
• What is the lowest temperature the part must remain operable at?
• What products (including cleaning agents) will be encountered?
• Is product contact continuous or intermittent?
• Is long term weather or ozone resistance important?

• Is there a specific surface finish required?
• What colour?
• What are the tolerances?
• If the component is moulded, what amount and position of flash is allowable?
