Injection Moulding Job Work for Your Own Mould
Send us your mould and specification. We run 100 ton, 200 ton and 250 ton machines to produce your components in bulk.
This page is for a factory or OEM that already has a mould and needs a shop floor to run it. We check the job first and confirm before we schedule production.
Who this job work service is for
Job work is a production arrangement. You keep ownership of the mould and the product, we run the machines to your approved specification.
Manufacturers with a full production line
Factories that already sell their own products but do not want to add another press for one mould or a seasonal order.
OEMs who need a specific part repeated
Companies that need a named plastic part produced in the same way, order after order, using their own die.
Battery and electrical companies with a mould
Useful where a crate, housing or cover already has a mould and simply needs a shop to run it.
Businesses with a machine that is down or missing
If the mould exists and your press is under repair, sold, or not yet installed, job work is the usual next step.
What you get on a job work order
We do not sell the finished part as a catalogue item. The output is your component, packed the way you ask.
-
Machine time on 100 ton, 200 ton or 250 ton presses, matched to your mould after we look at it. -
Trained operators for the full production run. -
Production against the specification you approve, not a generic in-house design. -
Packing and dispatch in the form you specify. -
A written confirmation before bulk production starts, so both sides agree on the same job.
Machine capacity
We run 100 ton, 200 ton and 250 ton injection moulding machines. Machine selection depends on your part size, the mould and the material, not on a fixed rule.

200T

250T

We assign a machine only after checking your mould size, the material and the part weight. A small part can still need a larger machine, depending on the mould.
How we handle a mould you send us
Most enquiries start with a mould that already exists. We look at it closely before we agree to run it.
You can send drawings, photos of the mould, or the mould itself for evaluation. Every mould is checked before we schedule it. Not every mould will fit our machines, and we will tell you plainly if it does not.
- 01You send mould and part details
- 02We check if the mould fits our machines
- 03We agree on production terms
- 04We run a trial if the job needs one
- 05You approve the trial part
- 06We run the full production order
- 07We pack and dispatch the parts
Parts we can produce
Below are examples. Whether your part fits depends on the mould and material, not on this list.
We do not claim that every listed part is suitable for every mould.
Industries that send us job work
These are common industries we work with. We do not claim to be certified specialists in any of them unless that is stated separately.
Why manufacturers choose job work over buying a press
No new machine to buy
Job work uses our press, not your capital. The mould is the only thing you need to already own.
Puts your mould to work
The mould already exists somewhere. Job work runs it without you buying new equipment or floor space.
Repeat orders stay simple
Once we approve the first run, later orders follow the same agreed process.
We do not publish savings numbers. Whether job work costs less than buying your own machine depends on your order volume and how often you would actually run it.
Production process
A typical enquiry follows this path. We do not skip the mould check to win the order faster.
Share your requirement
Send part details, mould data, material and the quantity you expect.
We check the mould
We confirm whether the part and mould suit 100T, 200T or 250T.
Trial run
We produce a sample for your approval where the job needs it.
You approve the trial
Once approved, we lock the specification for production.
Bulk production
We run your order to the agreed quantity.
Packing and dispatch
Finished parts are packed and sent as agreed.
How we talk about quality
We match the sample and specification you approve. We do not claim ISO certification or a fixed tolerance band unless we have actually measured it on your mould.
Existing manufacturing experience
We already produce battery crates for companies in the battery industry. This is real, ongoing mould based production, not a one off sample.
What customers need to provide
Send as many of these details as you can. Missing details only slow down the check, they do not stop the conversation.

Questions buyers ask on this search
What does job work mean in injection moulding?
It means you supply the mould and the specification. We supply the machine, the operators and the production run.
Can you use a mould we already own?
In most cases yes, after we check the mould size, weight and material against our machines.
What machines do you currently run?
We run 100 ton, 200 ton and 250 ton injection moulding machines.
Is there a weight limit for the part?
Practical production is usually up to around 300 grams, but this depends on the mould and material, not a fixed rule.
Do you produce in bulk?
Yes. Job work is meant for production quantities after a trial is approved, not single test pieces.
Can we place repeat orders?
Yes, once your first order is approved, later orders follow the same process, as long as the mould stays in good condition.
How do we send a mould for checking?
Start with photos, the mould size, number of cavities and material. We will tell you if it looks like a fit before anything ships.
