Manufacturing

Four ways to make your elastomer or polymer part. Send the drawing, we pick the route and check every batch before it ships.

CHOOSE THE ROUTE

The part picks the process.

Answer four quick questions and see which route fits your part.

Material family
Quantity per order
Thickest section
Bonded to a metal insert?

Example answers loaded: a thick cast PU part bonded to steel.

Hot-cast polyurethane
Suggested route

Hot-cast polyurethane

  • Thick sections cast and cure without the wall limits of injection moulding.

Also worth a look: Rubber compression / transfer moulding

ROUTE 01

Hot-cast polyurethane

Tougher than rubber at the same hardness, bonds straight onto steel, and the tooling is cheap enough for short runs.

Hardness
45 ShA to 75 ShD
Bonding
Onto steel hubs and plates
Batch size
1 to 5,000 parts
Used for
Wheels & rollersWear linersHeavy-duty rail and mining partsBonded steel assemblies
PU grades →
ROUTE 02

TPU & TPE injection moulding

Short cycles and the same size and hardness from the first part to the last. Our 200-tonne servo cell is set up for it.

Hardness
73 ShA to 75 ShD
Machine
200 T servo, dedicated dryer
Batch size
500 to 100,000+ parts
Used for
Rings & sealsBushesHousingsOvermoulded parts
TPU & TPE grades →
ROUTE 03

Rubber compression & transfer moulding

For large parts and rubber bonded to metal. Every compound batch is checked before it reaches the press.

Rubbers
NR, EPDM, NBR, CR, SBR
Hardness
40 to 90 ShA
Batch size
10 to 10,000 parts
Used for
Anti-vibration mountsTrack and rolling-stock partsSealsRubber-to-metal parts
Rubber compounds →
ROUTE 04

3D printing

Hold the part in your hand before any steel is cut.

A ₹2,000 print before a ₹2,00,000 mould catches fit problems while they are still cheap to fix.
Lead time
From 48 hours
Batch size
1 to 20 parts

FINISHING

Parts arrive ready to fit.

Finishing runs next to the presses, so nothing waits on another supplier.

Deflashing & trimming

Machining

Insert bonding

Post-cure

Assembly & kitting

Batch marking

QUALITY

Checked before, during and after every batch.

We check the material going in, the process while it runs and the part coming out. You get the records.

BeforePre-production

Inputs confirmed

Material, tool and inserts checked before the run.

DuringIn-process

Process held

First part measured against your drawing before the batch continues.

AfterFinal

Output verified

Size, hardness and finish verified and documented.

With every batch

  • First-article report
  • Material batch certificate
  • Hardness and dimension records

FAQ

Questions buyers ask first.

Is there a minimum order?

No fixed minimum. Cast PU and rubber moulding suit small batches; injection moulding pays back from a few hundred parts.

Can you make a part from a sample, without a drawing?

Yes. Send the sample and we quote from it. See reverse engineering.

Can you bond PU or rubber to our steel parts?

Yes. We prepare the steel in-house and bond PU or rubber onto it.

What documents come with a batch?

A first-article report on the first batch, then a batch certificate with every delivery. Full test reports on request.

How quickly can you start?

Prototypes from 48 hours. Your quote gives a date for each production step.

Where are the parts made?

At the group manufacturing and test facility Croslynk works with in Bengaluru.
