Injection Moulding v Blow Moulding

  1. 1. Injection Moulding v Blow Moulding
  2. 2. What is Injection Moulding?• Injection moulding is a manufacturing process for making parts from thermoplastic materials• Thermoplastics are materials, such as polystyrene, that can be formed into different shapes once heated and pressured in a mould• An engineer/industrial designer will design the desired product and then a mouldmaker will make a mould from metal• Used to manufacture a range of parts such as body panels for cars
  3. 3. What is Blow Moulding?• Blow moulding is a manufacturing process similar to injection moulding• Hollow plastic parts are formed through the use of blow moulding
  4. 4. Main Differences Injection Moulding Blow Moulding• Makes solid parts • Makes hollow parts• Thermoplastic is injected • Thermoplastic is a sheet/ into a mould parison that is pushed into a mould by air• A part’s thickness is • A part’s thickness will differ influenced by the mould and from place to place core relationship• 90% of the time spent on the • 50% of the time spent on the job is needed for making the job is needed for making the mould mould
  5. 5. Main Differences Injection Moulding Blow Moulding• Minimising the presence of • As a hollow interior is air in the injected plastic is a required, air is needed to key concern force the plastic to expand • The process may end in the• When the plastic cools at the first mould or the air may be end of the process the injected in another section machine opens and the part of the machine is released• Parts tend to be solid plastic • Parts tend to be hollow parts or components containers such as bottles
  6. 6. Injection Moulding
  7. 7. Blow MouldingExtrusion Blow Moulding – one of 3 types of Blow Moulding
  8. 8. Finding a Contract ManufacturerIf you are looking for a contract manufacturer who specialises in Plastic Injection Moulding and Blow Moulding consider a company that has ISO accreditation.Look for a company that has a short physical distance from the delivery point and a short lead time.Offers additional services such as market research and feasibility analysis.
