Injection moulding · Shrewsbury
From a sketch on the back of an envelope through CAD, simulation, FDM prints and steel tooling to production. Minimum order ten parts, no upper limit.
Straight answer on feasibility, usually same day.
Materials: PP, PE, PS, ABS, PC, PC/ABS, PMMA, POM, PA6, PA66, PBT, PET, TPE, TPU, PPS, PEI and PEEK, plus glass, talc and mineral filled grades. We also mould structured dielectrics for RF metamaterials.
You can come in at any stage. Some customers arrive with a finished model and a tool, others with an idea and a problem. Each service has a page of its own.
Send us a sketch, a sample or just the requirement and we will do the CAD. If you already have a model, we will review it for manufacture before any steel is cut.
We offer Moldflow as a consultation service on your design, or as a way of troubleshooting a tool that is already running. Normally used for new parts, but often used to find the cause of an existing problem.
Insert sets or complete moulds in steel or aluminium. The choice depends on how complex the part is and how many you need now and in the future. In special cases T1 samples can be ready in around 2 weeks. Once T1 samples are approved the same tooling can go on to produce up to 50,000 shots, so production parts stay consistent with the ones you signed off.
FDM 3D printing in-house, as a step on the way to a new tool or as parts in their own right.
Processing around a problem that is actually rooted in part or tool design is a fruitless exercise. It leads to instability and constant changes rather than a fix. We start with data: establish what the process is actually doing, using Moldflow where needed to give an inside view of what is happening in the cavity and aid root cause analysis. From there we determine whether the issue is process, part design or tool, define the real process window, set the process inside it and recommend the corrective action needed.
Ten parts is a genuine minimum, and there is no upper limit at the other end. Low volume and high volume run on the same tooling and to the same documented process, so a field trial batch and a production batch are the same.
Training run on your own shop floor, using your machines, your mould tools and your materials. Because the training happens on your equipment, the learning is 100% relevant to the participants. It is not a classroom example, it is the work in front of them.
Bringing an injection mould tool back to the UK from overseas, so that lead times, minimum order quantities and quality problems are all a phone call away rather than eight time zones away.
Enter the details you have: mould shut height, tie-bar dimensions, shot weight, projected area, whatever you happen to know. The checker runs it against our machines and tells you yes, borderline or no. Leave the rest blank.
No sign-up needed.
We are a small team of engineers. The person who sets your process is the one who answers the phone.

Notes on moulding, materials, tooling and process.
There is no technical minimum. Why moulders set one, what set-up does to the price of a small run and how ten parts still come out right.
