Question 1 Report

A batch of 500 identical acrylic components is required.

(a) Name a suitable process for producing this batch. [1]
(b) Explain two reasons why the process you have named suits this quantity. [2]

Answer Details
  1. (a) Laser cutting from acrylic sheet is suitable [1]. Injection moulding may also be accepted if its suitability is properly justified.
  2. (b) The profile is cut directly from a CAD file, so no mould or other dedicated tooling is required. This suits a batch of 500 because that quantity may be too small to repay the high fixed cost of making an injection mould [1]. Laser cutting also produces identical parts and leaves a flame-polished edge, removing a separate finishing operation [1].

The key comparison is between low set-up cost for laser cutting and high tooling cost for moulding.
