TAKING INTO ACCOUNT THE THERMAL EXPANSION & CONTRACTION WHEN MACHINING NYLON

TAKING INTO ACCOUNT THE THERMAL EXPANSION & CONTRACTION WHEN MACHINING NYLON

Thomas Cipriani – Product Specialist at Robco

When working with Nylon material, we must understand that it reacts to temperature fluctuation. The best procedure to follow when machining Nylon at the factory is to cut it to size at a temperature of about 75°F; if we don't, then we risk having dimensional issues later on. Nylon is a thermal plastic, hence it will expand when subjected to high temperatures and contract at low temperatures. Always take into account the installation temperature.

Here is a working formula to help you when machining Nylon based parts:

Here are some examples:

>A) Expansion Example:
Installing at 78°F the maximum operating temperature can reach 150°F and the piece is 120” long: 150° - 78° = 72° temperature change 72 x 120 x .00005 = .432” expansion

>B) Contraction Example:
Installing at 78°F the lowest operating temperature could reach -200°F and the piece is 120” long: 78° +20° = 98° temperature change 98 x 120 x .000067 = .788” contraction

If you follow these simple guidelines, you'll avoid headaches later on!

6 raisons pour lesquelles vous avez besoin de couvertures chauffantes sur vos conteneurs de liquides industriels pendant l'hiver

Les avantages des couvertures chauffantes pour les liquides industriels pendant les hivers rigoureux du Canada Lorsqu'il s'agit de gérer des liquides industriels pendant les rudes hivers canadiens, maintenir la bonne température est essentiel pour garantir l'efficacité et la sécurité. Que vous stockiez ou transportiez des produits chimiques, des huiles, des adhésifs ou d'autres matériaux sensibles dans des fûts, seaux ou cuves, les conditions de gel peuvent gravement affecter leur viscosité, leur utilisabilité et même causer des dommages irréversibles. Une solution pratique à ce problème est l'utilisation de couvertures chauffantes. Voici pourquoi elles sont indispensables pour les applications industrielles. 1. Prévention du gel et maintien du flux Les hivers canadiens apportent souvent des températures sous zéro, ce qui peut entraîner le gel des liquides industriels ou les rendre trop visqueux pour être efficacement utilisés. Les couvertures chauffantes ...

6 reasons why you need heating blankets on your industrial liquid containers during winter

The Benefits of Heated Covers for Industrial Liquids During Harsh Canadian Winters When it comes to handling industrial liquids during the brutal Canadian winters, maintaining the proper temperature is critical for efficiency and safety. Whether you're storing or transporting chemicals, oils, adhesives, or other sensitive materials in drums, pails, or totes, freezing conditions can severely impact their viscosity, usability, and even cause irreversible damage. One practical solution to this challenge is the use of heated covers or heating blankets. Here’s why they are essential for industrial applications. 1. Preventing Freezing and Maintaining Flow Canadian winters often bring sub-zero temperatures, which can cause industrial liquids to freeze or become too viscous to be effectively processed. Heated covers help maintain the fluidity of liquids by applying consistent, controlled warmth around drums, pails, or totes. This prevents costly downtime associated wi...

6 Reasons Why Removable Insulation Covers Are Essential in Hospitals

Why Removable Insulation Covers Are a Smart Investment for Hospitals In the complex environment of a hospital, efficiency, safety, and cost management are crucial. Every decision made must prioritize patient care, regulatory compliance, and operational efficiency. While often overlooked, insulation in hospitals plays a critical role in maintaining a safe and comfortable environment. One of the most effective and versatile solutions is the use of removable insulation covers, also known as removable insulation jackets. These covers are a smart investment for any healthcare facility, offering a range of benefits that directly impact the hospital’s bottom line and overall performance. 1. Energy Efficiency and Cost Savings Hospitals operate 24/7, making energy consumption a significant cost factor. Heating, ventilation, and air conditioning (HVAC) systems, along with various mechanical equipment, consume vast amounts of energy. Uninsulated or poorly insulated equipment can lead...
