Reduce Tire Manufacturing Cost

Rubber formulations that can be cured without traditional curatives like zinc oxide and sulfur. The formulations contain a statistical copolymer made from conjugated diene monomers and vinylbenzocyclobutane. When heated, the vinylbenzocyclobutane segments crosslink with each other and other double bonds in the polymer to cure the rubber without additional curatives. The statistical distribution of vinylbenzocyclobutane promotes even crosslinking density. The formulations are useful in tire applications as they reduce cost and environmental impact compared to traditional curing methods.

Manufacturing pneumatic tires that have improved cost, performance, and recyclability compared to conventional rubber tires. The manufacturing process involves making the carcass from cured rubber but the sidewalls and tread from thermoplastic elastomer (TPE). This allows the tire to still have the necessary elasticity for road contact while providing benefits like lower rolling resistance, better chemical resistance, improved recyclability, and reduced manufacturing time.

Automatically determining the optimal production parameters for manufacturing tires of specifications without requiring manual setting by operators. The method involves using historical production data for the target specification to determine the parameters that resulted in optimal performance. If such data exists, it is used to manufacture the target specification tires. If not, default parameters are used. This eliminates the need for operators to manually set parameters based on experience and avoids issues of excessive workload and error rate.

A method for optimizing tire production layout and capacity planning in a smart tire factory. The method involves calculating the required storage, equipment, personnel, and logistics for each tire production area based on the tire shipment target, demand parameters, and process qualification rates. This allows accurate modeling and parametric design of each area to optimize production efficiency, redundancy, and safety. By connecting optimized single processes with transition parameters, it enables integrated top-level control of the tire factory.

Non-pneumatic tires that can be manufactured in one molding operation using horizontal centrifugal casting (HSC) technology. The tires have a rigid inner rim that is molded together with the elastomeric tire body in a single mold rotation. The mold allows complex tread patterns and radial demolding of the tire. The rigid rim can be metallic. The HSC process enables molding the entire tire in one step without separate tread attachments.

Optimizing use of recycled rubber in tire production by identifying and managing recycled products. The method involves storing and reincorporating recycled complex products from machines to ensure consistent properties for downstream use. Recycled products are filled into containers, identified, and stored in a subsystem. When needed, specific containers are retrieved to meet production plans. This allows automated selection of recycled products that match required properties for upcoming mixes.

A modular system for molding tire treads that allows easy repair and replacement of damaged mold segments without needing to replace the entire mold. The system uses interchangeable dual mold segments with replaceable ribs that can be swapped when damaged. The segments have a groove for the ribs. Removable securement allows replacing just the rib instead of the whole segment. This reduces downtime and costs compared to replacing entire molds.

Method for increasing tire production capacity and efficiency in a tire manufacturing facility with multiple workstations. The method involves overlapping the work cycles at adjacent workstations to maximize throughput. It achieves this by having two forming drums at each workstation and transferring them between stations using robotic grippers. The process involves loading a tire onto one drum at a workstation, then before releasing that drum at the exit, capturing the second empty drum at the loading location. This allows both drums to be working simultaneously.

Method and plant for efficiently producing tires with improved quality by parallelizing the drum forming stations to reduce cycle time and improve accuracy. The method involves forming tire components like carcasses and treads simultaneously on multiple stations using robotic arms to move drums between stations. This allows faster production without interrupting drum movement for loading/unloading. The plant has multiple parallel workstations for each tire component to form them concurrently. This reduces overall cycle time compared to sequential drum loading/unloading. The robotic arms move the drums between stations instead of manual handling. This allows faster movement and precision placement compared to manual loading/unloading.

Optimizing the production of tire semi-finished products by allocating inventory balances to molding machines based on forecasted demand and work similarity, rather than fixed winding lengths per cart. The allocation process involves finding a combination of balances that meets or exceeds forecasted requirements for each machine. It preferentially allocates balances to machines with earliest expected usage. If balances exceed requirements, no plan is established. The remaining balances are divided into full and partial carts based on machine-specific winding lengths. This minimizes material shortages and standard replacement waste compared to fixed cart lengths. The allocation process is linked with the conveyance system to ensure allocated balances are transported to the assigned machines for consumption.

Double tire tread design for retreading that eliminates the need for buffing and cementing during retreading. The double tread has two opposite tread patterns molded on the same side of the tread body. When cut along the plane between the patterns, it separates into two single treads, each with a unique tread pattern. This allows applying one of the treads to each side of the tire casing without buffing or cementing.
