All About Delrin: The Amazing Plastic Material

What Is Delrin?

Delrin is a special plastic. Its real name is polyoxymethylene. A big company called DuPont made it in the 1960s. It is white and shiny when cut by machines. Think of Delrin like a super plastic. It is hard but can also bend without breaking. This makes it very good for many things. At Istar Machining, we work with Delrin all the time. We use CNC machining to make parts from this amazing plastic.

Why Delrin Is So Good

Delrin has many good things about it:

• It is very strong (70 MPa – that’s like 10,000 pounds pushing on a small spot!)
• It does not soak up water like other plastics
• It can stay strong even when very cold (-40°C)
• It can slide very well with little friction (0.15-0.3)
• It keeps its shape and does not change size much A test from Ford showed that Delrin parts in car seats were 15% lighter than metal and lasted 10% longer! This makes cars better and saves money.

Delrin vs. Other Plastics

Let’s see how Delrin is different from other plastics:

Delrin is stronger than nylon. It stays dry better than most plastics. When making gears or parts that move a lot, Delrin is the best choice. Our team at Istar Machining can help you pick the right plastic for your parts.

Where People Use Delrin

Delrin is used in many cool places:

In Factories

• Moving belts
• Rollers
• Sliding parts
• Gears that need to last long

In Cars

• Seat parts (saved 15% weight in Ford tests)
• Fuel tanks
• Safety belts
• Door parts

In Medical Things

• Breathing helpers
• Body parts that go inside people
• Tools doctors use

In Homes

• Zippers on clothes
• Toothbrushes that buzz
• Kitchen tools A big washing machine company saved 20% money and made parts 30% faster by using Delrin instead of metal!

How We Cut and Shape Delrin

At Istar Machining, we are experts in working with Delrin. Here is how we do it:

CNC Machining

We use sharp tools and smart machines to cut Delrin into any shape. Our CNC milling machines can make very small and exact cuts.

Tips for Working With Delrin

• Use sharp tools – dull tools make bad cuts
• Don’t squeeze too hard – Delrin can bend
• Keep it cool – too hot can harm Delrin
• Make slow cuts for best finish Delrin is great for CNC prototype machining when you need test parts fast.

Being Safe With Delrin

Delrin is safe to use, but you need to know some things:

• If it gets too hot (over 230°C), it can make bad air
• Keep it in a dry place
• Wear a mask if cutting a lot of Delrin
• It does not burn easily but is not fireproof

Delrin Numbers and Facts

Here are some important numbers about Delrin:

• Melting point: 175°C
• Strength: 70 MPa (very strong!)
• Friction: 0.15-0.3 (very slippery!)
• Water soak-up: Only 0.20% (stays dry!)
• Working heat: Up to 90°C for long time, 140°C for short time

When to Use Delrin

Delrin is best for:

• Parts that move and rub
• Things that need to be strong
• Places with some water or oil
• Parts that need to be exact sizes It is not good for:
• Very hot places
• Parts in strong chemicals
• Things in bright sun for long time

Real Stories of Delrin Success

Car Seat Story

Ford made seat parts with Delrin. They were lighter and lasted longer than metal parts. This made cars use less gas.

Kitchen Mixer Story

A company that makes kitchen mixers used Delrin gears instead of metal. They saved 20% cost and made them 30% faster. The mixers also ran more quiet.

Medical Tool Story

Doctors needed tools that could get wet and stay exact sizes. Delrin was perfect because it only soaks up 0.20% water compared to other plastics that soak up more.

How Istar Machining Works With Delrin

Our company, Istar Machining, is very good at making things from Delrin. We use 5-axis machining to cut Delrin into any shape you need. We can make:

• Small parts (tiny gears, pins)
• Big parts (panels, frames)
• Complex parts with holes and slots
• Smooth parts that slide well Our machines can cut Delrin with 0.01mm accuracy. That’s thinner than a human hair!

Comparing Delrin to Metals

Many people use Delrin instead of metal. Here’s why:

• It is lighter than metal
• It does not rust like metal
• It makes less noise when moving
• It costs less to make into shapes
• It does not need oil to move smooth In the Ford test, Delrin was 15% lighter than steel parts and lasted 10% longer!
