LESPLASTIQUES DECORES

About Us

To match polymer selection to real service conditions, so engineering plastics deliver the wear, chemical and weight advantages they are capable of.

Who We Are

About Our Company

LES PLASTIQUES DECORES supplies engineering plastics as stock shapes and as finished machined components, along with resin and compound supply for molders. Our material range spans ultra high molecular weight polyethylene, nylon in cast and extruded forms, acetal, polycarbonate, acrylic, PET, PTFE and filled fluoropolymers, PEEK, PPS, PVDF, polypropylene, PVC and high temperature and chemically resistant specialty polymers. We hold sheet, rod, tube and profile in a wide range of sizes, machine finished parts on computer controlled equipment, and fabricate assemblies by welding, bonding and forming.

Equipment builders and plant engineers around come to LES PLASTIQUES DECORES because polymer selection goes wrong in predictable ways. Nylon absorbs moisture and grows dimensionally, which ruins a tight tolerance part if nobody allowed for it. Acetal is dimensionally excellent and poor in strong acids. Polycarbonate is exceptionally tough and attacked by many solvents. Ultra high molecular weight polyethylene is superb in sliding wear and limited in temperature. We ask about load, speed, temperature, chemical contact, moisture and tolerance requirements, recommend accordingly, and machine with the stress relief and dimensional allowances that keep parts in print.

Engineering Plastics - About

Core Capabilities

  • Moisture conditioning and dimensional movement are accounted for in tolerances.
  • Wear components are reviewed against the failure mode they are replacing.
  • Food contact grades ship with the manufacturer's compliance documentation.
  • Material certificates are supplied and retained for traceable applications.
  • Material selection considers temperature, load, chemistry, speed and wear together.
  • Machined parts are inspected against the drawing before dispatch.

Our Mission

To machine plastics with the stress relief, tooling practice and dimensional allowances the materials actually require, rather than treating them as soft metal.

They told us a part should stay metal rather than selling us an expensive polymer. That conversation is why we now buy everything else from them.

Services

We machine plastics properly: stress relieved stock, correct tooling and feeds, dimensional allowance for moisture absorption and thermal movement, and inspection at stable temperature.

Our Services

What We Do

Wear Components & Conveyor Parts
Step 01

Wear Components & Conveyor Parts

Wear strips, chain guides, star wheels, timing screws, bearings, bushings, rollers and sprockets in self-lubricating polymers that eliminate greasing, reduce noise and protect the metal running against them. Material choice balances wear rate, coefficient of friction, temperature and load.

Precision Plastic Machining
Step 02

Precision Plastic Machining

Computer controlled milling and turning of plastic components with stress relieved stock, tooling and feeds selected for the polymer, and dimensional allowance for moisture absorption and thermal movement. Plastics machined like metal come off the machine in tolerance and move afterwards, which is why practice matters.

Material Selection & Technical Support
Step 03

Material Selection & Technical Support

Application review covering load, speed, temperature, chemical contact, moisture exposure, regulatory requirements, tolerance needs and cost, with honest guidance including cases where a cheaper material is entirely adequate or a metal component should stay metal.

High Performance & Chemical Resistant Polymers
Step 04

High Performance & Chemical Resistant Polymers

PEEK, PPS, PVDF, PTFE and filled fluoropolymers, polyimides and other high temperature or chemically resistant materials for demanding service in chemical processing, semiconductor, energy and medical applications, with grade selection against the specific exposure.

Resin & Compound Supply
Step 05

Resin & Compound Supply

Supply of engineering resins, compounds, masterbatch and additives to molders and extruders, with grade selection support, drying guidance and processing parameter advice. Many molding defects trace to inadequate drying of hygroscopic resins rather than to tooling or machine issues.

Request a Quote
Fabrication, Welding & Assembly
Step 06

Fabrication, Welding & Assembly

Plastic fabrication including hot gas and extrusion welding, bonding, forming, bending and assembly for tanks, enclosures, guarding, hoppers and ductwork, with joint design suited to the polymer. Not every engineering plastic can be welded, which affects design before it affects fabrication.

Stock Shapes: Sheet, Rod, Tube & Profile
Step 07

Stock Shapes: Sheet, Rod, Tube & Profile

Extensive inventory of sheet, rod, tube and profile across engineering and commodity polymers in a broad range of sizes, with cut-to-size service. Having material on the shelf matters because a replacement wear strip or guide is usually needed the same week the machine stops, not the following month.

Request a Quote
Food Grade & Regulated Applications
Step 08

Food Grade & Regulated Applications

Materials with appropriate food contact compliance documentation for processing and packaging equipment, including detectable polymers where foreign body control programs require them. Compliance documentation is supplied with the material rather than requested after an audit question.

Questions & Answers

Frequently Asked Questions

Sometimes, and it brings weight, corrosion resistance, noise reduction and lubrication-free operation. But temperature limits, creep under sustained load and thermal expansion all have to be checked. We will tell you honestly when the part should stay metal.

Not reliably. Plastics need different tooling geometry, feeds and speeds, careful heat management and, importantly, stress relieved stock. Parts machined without those considerations come off in tolerance and move afterwards as internal stress relaxes.

Yes, with compliance documentation supplied alongside the material, including metal detectable and x-ray visible grades where your foreign body control program requires them. Tell us the requirement at enquiry so the right grade is quoted.

Moisture absorption. Nylon takes up moisture from the air and grows dimensionally, so a part machined dry and in tolerance will move. The fix is dimensional allowance for the expected conditions, or a grade with lower moisture uptake.

It depends on load, speed, temperature, the mating surface and whether contamination or chemicals are present. Ultra high molecular weight polyethylene excels in sliding wear at moderate temperature; acetal offers dimensional stability; filled nylons handle higher loads. The duty decides.

Frequently it is resin drying rather than resin quality. Hygroscopic engineering resins molded without adequate drying produce surface defects and property shortfalls that get blamed on tooling and machine settings for months. Drying is the first thing to check.

Our Process

How We Work

  1. 1

    Review The Application

    We establish load, speed, operating and peak temperatures, chemical and moisture exposure, tolerance requirements, regulatory constraints and whether the part will be machined, fabricated or molded.

  2. 2

    Recommend Material

    A polymer and grade are proposed with the reasoning stated, including dimensional stability, wear behavior and any limitations, plus alternatives where cost and performance trade off.

  3. 3

    Supply Or Machine

    Stock is cut and supplied, or components are machined from stress relieved material with polymer-appropriate tooling and inspection at stable temperature.

  4. 4

    Verify & Support

    Dimensions are verified, documentation supplied where compliance applies, and in-service performance reviewed so material selection can be refined if the duty proves different from expectation.
