Material Selection Guide
Which Engineering Plastic Fits Your Application?
A practical comparison written by our production engineers to help buyers shortlist the right polymer before requesting technical data.
| Material | Key Strengths | Typical Applications | Available Forms |
|---|---|---|---|
| NylonPA6 / MC Cast Nylon | High wear and impact resistance, toughness, self-lubricating; lighter than bronze for many bushing uses | Gears, sheaves, rollers, wear pads, bushings, crane outrigger pads | |
| POMAcetal / Polyoxymethylene | High stiffness, very low moisture absorption, excellent dimensional stability and low friction | Precision gears, valve parts, bearings, food machinery components | |
| HDPEHigh-Density Polyethylene | Good chemical and moisture resistance, impact strength, easy to cut, weld and fabricate | Cutting boards, tank linings, marine fenders, outdoor fabrication | |
| UHMWPEUltra-High Molecular Weight PE | Outstanding abrasion resistance, very low friction, high impact strength even at low temperatures | Chute and hopper liners, conveyor wear strips, truck bed liners | |
| ABSAcrylonitrile Butadiene Styrene | Good impact strength, easy to machine and thermoform, smooth surface finish | Prototypes, housings, fixtures, display and model making | |
| PPPolypropylene | Excellent resistance to acids and alkalis, lightweight, weldable | Chemical tanks, electroplating equipment, water treatment, storage boxes | |
| PTFE & PEEKHigh-Performance Polymers | PTFE: near-universal chemical resistance and the lowest friction; PEEK: high strength at elevated temperatures | Seals, insulators, semiconductor and chemical-process parts |
Tip: For load-bearing wear parts in wet environments, POM usually holds tighter tolerances than nylon; for heavy impact and abrasive loads, cast nylon or UHMWPE typically lasts longer. Share your operating conditions and our engineers will recommend a grade.
How We Work
From Polymer to Precision Part: Our Production Process
Every order follows a documented workflow so that what you approve on paper is exactly what arrives at your dock.
01
Requirement Review
We confirm material, dimensions, tolerance, color and quantity from your drawing or sample.
02
Material Production
Sheets, rods and tubes are cast or extruded, then cooled under control to reduce internal stress.
03
CNC Machining
Turning, milling and drilling turn stock into finished parts that match the approved drawing.
04
Inspection
Dimensions, appearance and surface finish are checked before goods move to packing.
05
Export Packing
Goods are protected and labeled for sea, air or express delivery to your destination.

Buyer FAQ
Answers for Procurement & Engineering Teams
Straight answers to the questions overseas buyers ask most before placing their first order with us.
Which engineering plastics does SHUNDA manufacture?
We produce nylon (PA6 and MC cast nylon), POM (acetal), HDPE, UHMWPE, ABS and PP as sheets, rods and tubes, and machine custom parts from these materials as well as PTFE and PEEK. See the full range on our products page.
Can you produce custom CNC machined plastic parts from my drawings?
Yes. Send 2D or 3D drawings (PDF, DWG, DXF or STEP) with material, quantity and application details. Our engineers review tolerances, recommend a suitable polymer and confirm the manufacturing route before production. Learn more about our CNC machined parts.
How do I choose between nylon and POM for wear parts?
Choose cast nylon for heavy loads, impact and abrasive wear such as sheaves, rollers and wear pads. Choose POM when you need tight dimensional stability, low moisture absorption and low friction, for example precision gears, valve components and bushings in humid environments.
How fast does SHUNDA respond to inquiries?
Our sales team typically replies to email inquiries within 12 hours on working days. Including drawings, material and quantity in your first message helps us reply with complete information.
Where is the SHUNDA factory located?
Our factory is in Henglan Town, Xinhe County, Xingtai City, Hebei Province, China. We ship engineering plastic products worldwide; details are on our Global Service page.
