It\u2019s a common enough issue.\u00a0 Your current overseas manufacturing partner very helpfully helped to design your components and manufactured your tooling, but now you\u2019re stuck with them!<\/strong><\/p>\n

This informative case study from LVS Quality Measurement Services demonstrates how they worked around this common issue.<\/strong><\/p>\n

<\/p>\n

Telford based LVS QMS<\/a> have the equipment and skill sets to allow them to work backwards from a sample component.\u00a0 They can accurately measure external and internal features and then \u2018digitalise\u2019 these datum points to produce a fully rendered and dimensioned 3D model.\u00a0 This CAD file can then be used to manufacture new tooling.<\/p>\n

However, their in-depth knowledge of component design and material selection allows them to also enhance a product, i.e., rather than just making an exact duplicate.\u00a0 After all, if you are going to the expense of having a new production tool produced, why not also launch version 2.0 of your product.<\/p>\n

Here is a recent example of a project undertaken for a very \u2018high-end\u2019 automotive client.\u00a0 In this case, their customer wanted to improve an existing product but no longer had the original drawings.<\/p>\n

The brief was to replace an existing method for topping up an under-bonnet hydraulic oil reservoir.\u00a0 This was traditionally done by removing the sealing cap from a plastic bottle containing the oil, then inserting a bung into the bottle’s neck that incorporated a silicone tube with an end probe that was inserted into the reservoir.<\/p>\n

Stage one <\/strong>was to accurately measure the \u2018male\u2019 thread form of the bottle, which was non-uniform rather than matching a known standard.\u00a0 This was done using a Contour Measurement Machine and used to produce a circular digital rendering of the thread.\u00a0 Specialist software then generated a mirror thread, i.e. as a female form that could be incorporated into the new assembly.<\/p>\n

\u00a0<\/em><\/p>\n

Stage two <\/strong>involved the measurement and digital rendering of the original solid bottle cap, as well as the end probe.<\/p>\n

Stage three <\/strong>required the now completely modelled old components to be combined into a new cap design with an integrated hose-tail section, the later copied from the end probe.\u00a0 A new internal sealing ring was also designed and added, this to prevent leakage when the oil bottle is inverted.<\/p>\n

Stage four <\/strong>involved the selection of a suitable plastic material, in this case, HDPE.\u00a0 Allowances were then made for material shrinkage rates, as well as the required tolerances for thread meshing and sealing surfaces.<\/p>\n

Stage five <\/strong>required production tooling to be manufactured for all components.<\/p>\n

Stage six <\/strong>was the final stage, sister company LVS Small Plastic Parts initially sampling the tools, before moving to mass production and assembly.<\/p>\n
