Customized cast polyurethane products can meet the differentiated requirements of parts performance, size, and structure in different application scenarios. Polyurethane materials are ideal for heavy-duty wheels, guide wheels, rollers, seals, cushions, and other products due to their excellent wear resistance, impact resistance, corrosion resistance, and high load-bearing capacity. This article will analyze the customized solutions for polyurethane wheels and other products from three dimensions: the importance of customization, process flow and manufacturer selection.
The importance of customized polyurethane products
1. Accurately match the needs of application scenarios
The hardness, elasticity, temperature resistance range, and other properties of polyurethane materials can be flexibly controlled through formula adjustment. For example:
High-load forklift wheels in the logistics industry require ultra-high hardness and tear resistance.
Silent wheels for medical equipment need to take into account a low friction coefficient and shock absorption performance.
Tires for outdoor machinery need to withstand extreme temperatures and chemical corrosion.
Customized production can design material formulas in a targeted manner to ensure that the product is perfectly matched with the use environment.
2. Extend service life and reduce overall costs
Customized products can avoid frequent replacement or equipment damage caused by performance mismatch. For example, after a certain automobile production line adopted customized polyurethane guide wheels, the downtime caused by wear was reduced by 60%, and the comprehensive maintenance cost was reduced by 35%.
3. Support non-standard design and functional integration
The customized casting process can flexibly design special-shaped structures (such as embedded metal skeletons, special grooves), customize the outer diameter, thickness, aperture, tolerance, and other parameters to meet the needs of lightweight and high-precision installation, and help equipment innovation and upgrading.
Key steps for customized cast polyurethane products
1. Demand analysis and solution design
Manufacturers need to communicate with customers in depth about application scenarios, load capacity, environmental factors, friction frequency, etc., clarify the core parameters of the product, such as hardness (Shore A/D), metal core structure, compressive strength, temperature resistance range, etc., and design product drawings.
2. Customized material formula
Engineers select suitable polyurethane materials (NDI/TDI/MDIsystem or nylon, etc.) according to working conditions.
3. Mold design and manufacturing
Use CNC processing or 3D printing technology to make high-precision molds to ensure that the product size tolerance is controlled within ±0.1mm, and optimize the demolding structure to reduce defects.
4. Casting and vulcanization
The air bubbles are removed through the rotary casting process, and the vulcanization reaction is carried out under a constant temperature environment to ensure that the molecular structure of the material is uniform and stable.
5. Post-processing and quality inspection
After trimming and grinding, the hardness, size, adhesion, and wear resistance are inspected before leaving the factory to ensure that the product meets industry standards (such as ISO 4649 wear resistance test).
Core considerations for selecting high-quality manufacturers
1. Raw material control: High-quality manufacturers use imported prepolymers and additives to ensure performance stability.
2. Strong technical capabilities: with independent formula R&D capabilities and an engineering team, they can quickly respond to complex customization needs;
3. Advanced equipment: using fully automatic metering and pouring systems and CNC processing equipment to ensure product accuracy and consistency;
4. Timely service: from design to delivery, there is complete process control, and sample trial installation, batch customization, and after-sales technical support can be provided.
5. Rich experience: many years of service in the crane, logistics equipment, wind power, high-speed rail, coal mines, food, electronics, and other industries, and understand the needs of various working conditions;
6. Perfect quality assurance system: through ISO quality system certification, products have passed ROHS, REACH, and other environmental protection and performance tests.
