What is CNC Machining Polyethylene(PE)?

Polyethylene is short for PE,is a kind of thermoplastic resin.Polyethylene/PE is odorless, non-toxic, feels like wax, has excellent low temperature resistance, good chemical stability, and can resist the erosion of most acids and bases. Insoluble in general solvents at room temperature, small water absorption, excellent electrical insulation.CNC machining Polyethylene( PE) is a process that applies computer-controlled digital technology to remove the extra material and complete any necessary cutting, turning or milling. This can be done with machine tools depending on what's needed for your specific programmings before getting an end product from Polyethylene(PE) in their final form.

What are the benefits of CNC Machining Polyethylene(PE)?

Polyethylene (PE) is a thermoplastic with high strength-to-weight ratio, good impact strength and excellent weather resistance.This makes Polyethylene (PE) is an excellent material for CNC machining operations,such as excellent machinability and rigidity. Its low moisture absorption also makes it appropriate for marine applications, medical industry, and other sanitary industry applications.

1) Polyethylene has good tensile strength, creep resistance is not good, but the impact resistance is good.

2) Polyethylene has low heat resistance, good low temperature resistance.

3) Because polyethylene is non-polar, it has excellent electrical properties of low dielectric loss and high dielectric strength, that is, it can be used as FM insulating material, corona resistant plastic, and high voltage insulating material.

4) Polyethylene has good chemical stability. It is resistant to corrosion by aqueous solutions of acids, alkalis and salts at room temperature.

Justin, CEO of a lighting company

I inspected the top two pieces of all five boxes. Everything is beautiful! BEAUTIFUL! You remove so much stress from my shoulders. I know that when we pay you to manufacture a product, it will be made perfectly. The glass bead blasting and anodizing is always beautiful. I am so very happy! You make it easier for us to run our business. There is no trouble! With most factories, I have a moment of fear before I open their boxes. Will the components be made correctly? Do they care about quality? It is often a war. And Dennis has to fight the war, treating most factories like small children! But, not your company. You’re company is world-class. You make beautiful components!Thank you very much for your hard work. We will work together for many lifetimes!

David, General manager for a family owned business

I’ve been working with Chinese manufacturers since 2004 and had some really unfortunate partnerships until 2012 when we partnered with Worthy Hardware. At first,we only gave them small orders to test and make the start. However,their response speed was very fast ,and their engineers help us improved our designs more simple, this helped us reduce a lot of cost.Our cooperate is more and more stable! We trust Worthy Hardware always ,very responsible. Your guys are great! .Worthy Hardware is by far my favorite, because of the way they handle business and the quality of what they make.If you are from USA and would like to know more about Worthy Hardware,i would be very happy to be as an endorsement.


CNC Machining Polyethylene (PE) FAQ

1. What is the applications for CNC machining Polyethylene (PE)?

High-density polyethylene (HDPE) is a highly durable material with many applications. It can be used in industries such as CNC machining where tight tolerances and precision are required for specific areas on parts made from this plastic, or as an excellent alternative to other plastics because it does not contribute fibers which could cause problems during recycling process like impurities caught by filters at factory level .
Meanwhile,as a new type of polymer material.PE is made to sheets, pipes and rods,they are widely used in every corner of production and life, and gradually replaced traditional plastics.
Conveyor guides
Chute liners
Chemical holding tanks
Food processing parts
Medical equipment
Packaging applications
Conveyor wear strips (HDPE)
Piping systems (HDPE)
Liquid dispensing equipment (HDPE)
Marine components (HDPE)

2. How many types for Polyethylene(PE)?

There are 3 types for Polyethylene( PE):HDPE,LDPE and LLDPE
HDPE,High-density polyethylene, is a light weight and impact resistant thermoplastic.It is white color,the crystallinity is 80% to 90%,the softening point is 125- 135°C, temperature is 100°C.Its hardness, tensile strength and creep properties are better than low-density polyethylene (LDPE).
LDPE,low-density polyethylene, with 0.920 g/cm3 density, andmelting point 130℃~145℃.It can withstand the erosion of most acids and alkalis, has low water absorption, maintains flexibility at low temperatures, and has high electrical insulation.
Compared with LDPE, LLDPE (Linear low-density polyethylene) has excellent environmental stress cracking resistance and electrical insulation, higher heat resistance, impact resistance and puncture resistance, etc.
Among the above three types polyethylene, HDPE is frequently used for CNC machining process duo to its hardness,high strength.Worthy Hardware is always processing HDPE and other plastic parts to customer specifications, drawings or samples, our CNC machine and tools cater for specific engineering plastic materials with flexible milling, turning or machining services.
