Plastic profile extrusion is how we make long, continuous plastic shapes. Think of it like a Play-Doh extruder, but for industrial plastic.
We melt plastic pellets and push them through a custom-made metal die. The die has a hole shaped exactly like the profile you need. As the plastic comes out, it cools and hardens into your profile shape.
We can make almost any 2D cross-section shape. Simple strips, complex hollow channels, sealing lips, T-shapes, U-channels, and multi-chamber profiles.
Any cross-section, any RAL or Pantone colour.
The die is the single most important part of profile extrusion, since it determines the final shape, wall thickness, and dimensional accuracy of the profile. PlasCity designs and machines every extrusion die in house rather than outsourcing tooling. Our team maps out the flow channel to balance melt flow across the full cross section, so complex shapes with multiple walls or hollow chambers come out even rather than warped on one side. Most dies take two to four weeks from design approval to first trial run, and we produce and check trial samples before committing to bulk production.
Send a physical sample of a discontinued or competitor profile. Our chemical engineers identify the compound and our in-house die shop cuts a matching die ideal for buyers switching suppliers or replacing an obsolete profile.

| Material | Best For | Key Property | Flexibility |
|---|---|---|---|
| PVC | Seals, windows, HVAC, refrigeration, furniture | Durable, chemical resistant, low cost | Rigid or Flexible |
| HDPE | Pipes, outdoor use, chemical containers | Tough, weather resistant, food safe | Semi-rigid |
| ABS | Automotive, electronics, industrial trim | Impact resistant, easy to paint | Rigid |
| PP | Food contact, medical, packaging, automotive | Lightweight, heat resistant, chemical resistant | Rigid to semi-rigid |
| Nylon | Mechanical parts, wear surfaces, guides | Very strong, wear resistant, self-lubricating | Rigid |
| TPE / TPR | Seals, grips, flexible trim, co-extrusion | Rubber-like, soft touch, weather resistant | Very Flexible |
Six simple steps. We handle everything from die design to delivery.
At PlasCity, plastic profile extrusion means taking a customer's drawing or physical sample, machining a matching die in house, and running that die on one of our 13 extrusion machines to produce the exact profile shape needed, in the material, colour, and length specified. For the general engineering explanation of how extrusion works as a process, see our Plastic Extrusion Guide.
Profile extrusions are plastic parts with a constant cross sectional shape running their full length, such as a seal, channel, or trim strip. This is different from an injection moulded part, which is an individual three dimensional shape produced one piece at a time in an enclosed mould.
Our production runs typically start at 3,000 metres for extrusion and 5,000 pieces for injection molding. This reflects the scale we are set up to manufacture at consistently. For specific project needs outside this range, contact us directly to discuss options.
Yes. Send us a physical sample of your existing or discontinued profile. PlasCity's chemical engineers identify the material compound and PlasCity's in-house die shop cuts a matching die — this is a standard service for buyers switching suppliers or replacing an obsolete profile.
Yes. PlasCity exports plastic profiles to the UAE, Saudi Arabia, UK, USA, and other countries. PlasCity handles all export documentation and can arrange shipping from its factory in Lahore, Pakistan.
To get a custom plastic extruded profile made, send PlasCity your drawing, DXF file, or a physical sample through our contact form or WhatsApp. Our engineers review it and respond with a quotation within one business day, covering tooling cost, per metre pricing, and lead time. There is no separate online ordering catalogue, every order starts with a direct enquiry so we can confirm material, tolerance, and finish before quoting.
Yes. PlasCity does not sell stock catalogue profiles, every product is made to the customer's own drawing or sample. Our engineers review the design for manufacturability before quoting, and can suggest adjustments that reduce material use or improve fit without changing the part's function.
