Calenderless Tire Manufacturing

What is Calenderless Tire Manufacturing?

For years, tire manufacturing has relied on the calendering process to produce the reinforced  rubber materials that are used to create the components within a tire. Calenderless Tire manufacturing relies on extrusion to create these same tire components.  

In this post, we will explore the calendering process more in-depth, and you will discover how going calenderless can be a great advantage to your company.

Advantages of Going Calenderless

The future of tire manufacturing is here. Discover the benefits of calenderless tire production. 

Lower Total Cost of Ownership

When you’re considering an investment in tire technology, it’s critical to assess the entire cost of ownership – not just operation. When you choose Steelastic’s proprietary calenderless system, you can save money. Here’s how:  

Lower Cost of Equipment

Equipment can be a huge capital investment, but it doesn’t have to be. If you are planning to produce fewer than 6 million  tires per year, the cost of Steelastic’s calenderless system might be for you. With a lower investment, tire manufacturers can pay off their equipment more quickly and receive a quicker return on their investment.  

No Special Foundation is Required

Traditional calendering equipment is large and heavy, requiring a special foundation and additional cost. When you choose Steelastic, you don’t need to lay a new foundation.  

Lower Utility Usage

Tire production requires a variety of utilities, but when you choose a calenderless tire production process, your annual cost is far lower. In fact, if you’re producing 6 million tires per year, your annual savings could be nearly $500,000. That’s a 12% savings in operating costs that goes straight to your bottom line.

More Flexible

A hallmark of the calenderless tire manufacturing systems is its modular design that allows for quick changeovers, lending itself well to flexibility.  

Tire manufacturers can process a variety of materials, including steel, aramids, nylon, fiberglass, rayon, polyester and more, making it well suited for multi-SKU applications.  

Quicker Delivery

The typical lead time for a calenderless tire manufacturing system is 50-54 weeks depending on the size and complexity of the equipment. Due to the small footprint and more simple nature of the machine, tire manufacturers can expect an installation time of 2-3 weeks. This is nearly half of the installation time needed for a traditional calenderless system.   

Lean Operation

Efficient Human Resources

A traditional calendering system requires multiple workers, but a calenderless cutter system requires only one. This allows plant managers to utilize workers more efficiently in other parts of the tire production process.  

The simple design of the calenderless system expedites the training process, allowing workers to be fully trained in months, as opposed to years of training required for the traditional calender component preparation production methods.  

Less Waste

When you go calenderless, you create less waste. It’s a single extrusion process, from raw materials such as cord and compound to a finished component. Without a need to stage calender material, the calenderless system produces less than 1% overall scrap.  

Higher Quality

The calenderless system gives precision belt width, gauge and angle control, resulting in higher production control and consistency. In fact, the combined cutting and splitting operation found in the calenderless system ensures that splicing is highly repeatable and consistent. This creates higher quality tires with a straight belt edge and improved cord control and position—and superior rubber-to-cord adhesion.

The Pros and Cons of a Calenderless System

Calenderless Cell

Since 1970, the Steelastic Company has been moving the world forward with tire technology. We offer most of the equipment you need for tire component manufacturing, offering products for both the traditional calender and calenderless manufacturing.  

What is ‘calenderless’ tire manufacturing?  

Calenderless tire manufacturing combines principles of lean manufacturing with the latest tire technology. Traditionally, tire manufacturers rely on calendaring to process their rubber into components that can be used for tire construction.  

As time and technology progress, some things change. And that can be a good thing.  

Steelastic’s calenderless tire manufacturing system is an extrusion-based system that produces belt/breaker, body ply, cap strip, inner liner, sidewall, tread, and bead apex. But what’s so great about going calenderless anyway?  

The Pros of a Calenderless Tire Manufacturing System 

Reduced Wastage

A calenderless system allows tire manufacturers to produce shorter runs of various tire types and sizes. This reduces waste, as it allows tire manufacturers to produce different types of tires, without wasting resources for a longer run on the manufacturing line.  

Lower Cost

When waste is reduced, it lowers the overall manufacturing costs and increases net profits.  

Additionally, when companies go calenderless, they no longer need expensive and bulky calendaring equipment or off-line processing equipment.  

Increased Efficiency

A calenderless system is a more efficient use of resources, time and labor. As an automated process, it reduces labor costs, and cycle time, while increases production capacity so you can hit your goals for manufacturing and profit margins.  

Increased Quality Control

Traditional calendaring requires precise measurements on large production volumes that are difficult to obtain. Using a calenderless system inherently reduces the complexity of the system and ensures the highest quality for your tire manufacturing company.  

Complexity of System

A calenderless tire manufacturing system is a single cell operation.   Raw materials are input into the system and finished tire component preparation materials are produced.   While it has a smaller footprint and requires less overall equipment, it is not a simple machine. However, the complex nature of a calenderless system is much less than that of the calender solution.  First of all, the calenderless equipment can be supplied in two thirds of the time frame of the calendered solution.  Also, operators can be training to be experts is months as opposed to years.  However, at Steelastic, we understand that our customers still need our support and that’s why we offer 24/7 service support that is available on the phone, online or in-person, and strategically placed around the globe to offer support when you need it most.  

The Cons of a Calenderless Tire Manufacturing System 

Large Capacity Tire Production Requirements

The calenderless system cannot match the production volume capabilities of a calender system.  The calender process is capable of mass producing a singular specification material at a very high rate.   This tends to lead to a slight advantage to calendered solutions on facilities that produce more than 6-7 million tires per year.   

Initial Cost of Installation for large volume plants

Every change in manufacturing systems has a cost, or investment, depending on how you look at it. While a calenderless tire manufacturing system is costly, we think that the efficiency and flexibility gained makes it a worthwhile investment in the future of tire manufacturing.
