Apply NowSenior Injection Moulding Technician
Location: South Leicestershire (commutable from Leicester, Rugby, Hinckley and Market Harborough)
Salary: £35,000 – £45,000 + [benefits]
Hours: Days
Type: Permanent
The role
Xia Engineering is recruiting a Senior Injection Moulding Technician for an established plastics manufacturer in South Leicestershire. This isn’t a role running the same tool for weeks at a time. The work is small-batch and varied, with lots of T0 trials on new tools, plus a large amount of insert moulding and overmoulding.
You’ll report to the Mould Shop Supervisor and be the go-to technical person on the shop floor. You’ll get new tools from first shot to a stable, validated process, handle frequent changeovers and keep quality right on short runs where there’s little room to fine-tune.
This day-shift role suits a technician who likes variety and a technical challenge, and who gets satisfaction from proving out a new tool.
What you’ll be doing
* Running T0 trials and mould sampling on new tools, developing robust processes and supporting process validation
* Setting up insert moulding and overmoulding jobs, including insert loading, positioning, and checks on bonding and encapsulation
* Making frequent tool and material changes on small-batch work, setting machines from zero to spec quickly and accurately
* Checking that material, masterbatch and inserts match each job, and using the correct jigs, fixtures and auxiliary equipment
* Carrying out first-off inspections and getting approval before production starts
* Leading troubleshooting on moulding defects and process problems, and optimising cycle times without affecting quality
* Finding and fixing material feed and drying issues
* Working closely with QC and Toolmakers on tool modifications, trial feedback and recurring problems
* Responding to machine alarms, finding the root cause and doing basic maintenance (oil, water flow, heater bands, air lines, filters, O-rings, sensors, hoses)
* Reporting cycle time and scrap variances, and keeping the work cell safe, clean and organised
What you’ll need
* At least 5 years’ experience setting and processing on injection moulding machines
* Hands-on experience of tool trials and sampling, from T0 through to process sign-off
* Experience of insert moulding and/or overmoulding
* Comfort with high-mix, low-volume work and frequent changeovers
* Strong process knowledge and a methodical approach to troubleshooting defects
* Close attention to detail and a solid awareness of health and safety
Nice to have
* Experience on Engel, Arburg or Sumitomo machines
* Experience with robotic handling or automation in moulding
* Knowledge of ISO 9001 or similar quality systems
* Scientific moulding or formal plastics processing training
What’s on offer
* £35,000 – £45,000, depending on experience
* Days, so no shifts or nights, although flexibility will be required.
* Varied, technically interesting work rather than repetitive production
