Hot Coil Manufacturing Processes
Hot coils refer to coiled springs that are manufactured at elevated temperatures. The hot coiling process enhances the metal’s formability, creating industrial springs with specific mechanical properties. Here are the different manufacturing processes involved in this technique:
Hot Rolling
Hot rolling is a metalworking process where the material is subjected to high temperatures and passed through rollers. It aims to decrease the metal’s thickness before shaping it into a coil. The elevated temperatures during hot rolling make the material more malleable and enhance its formability. This enables the creation of hot-coiled springs with specific design requirements.
Heat Treatment
Following hot coiling, heat treatment refines the material’s microstructure and enhances mechanical properties. The process involves quenching, which rapidly cools the hot-coiled springs, followed by tempering to achieve the desired hardness, strength, and resilience. Quenching adds hardness by freezing the microstructure, while tempering reduces brittleness and optimizes toughness.
Shot Blasting
Shot blasting is a surface treatment method where abrasive particles are propelled at high velocity onto hot-coiled springs. This process enhances the surface finish by removing any scale or oxidation formed during the hot manufacturing processes. The result is an improved appearance of the springs and better corrosion resistance.
The Process of Designing Custom Springs
Free Consultation
Our free consultation explores the application of your spring. We find solutions to questions such as ‘What is its failure mode?’ and ‘Are you looking to improve an existing design, or does it need to be lighter, stronger and more corrosion resistant?’
Spring Specifications
We explore limiting factors and evaluate the final dimensions, then create a suitable production drawing that meets all of your requirements.
Material Research
We carry out material research, considering factors such as tensile strength, durability, efficiency and corrosion resistance, to find the best material for you.
New Design
Our spring technicians then develop a new coil spring design using the most advanced spring software programme - Optispring. Plus, we book a feedback session with you to evaluate the success of the design.
Prototypes & Samples
We deliver manufactured metal spring samples so that you can test them in real-world applications. This guarantees that you are happy with the spring and that it is reaching optimal performance before going into production.
Quality Check
Our quality team will then review various aspects of the process, including the initial drawings, testing procedures, powder coatings, and print markings, and then carry out the Almen Arc test. These steps ensure you are satisfied with every step of the approval process - and then production begins!
