5" X 2" Polyurethane On Cast Iron Wheel

Our company was founded in 2007 and has been committed to the research and development, production, and sales of polyurethane products since its establishment. The company is located in Yantai, Shandong, the birthplace of polyurethane products. We have unique advantages in technical support, and after years of development, we have a strong technical team, production team, and sales team. China's large raw material manufacturer Wanhua is also located here, which has great advantages in raw material procurement and transportation cost savings. The 5 "x 2" Polyurethane on Cast Iron Wheel produced has received unanimous praise from customers for its high quality and reasonable price.

When producing 5 "x 2" Polyurethane on Cast Iron Wheel, the following points should be noted:

1. The mold needs to have good sealing and be easy to demold.
The thermal balance of polyurethane must be considered during design. If uneven heating occurs during the vulcanization process, it can easily lead to incomplete vulcanization, reduced strength, and even cracking at the joint between the iron core and polyurethane.
2. Core processing and bonding
The surface treatment of the iron core is crucial, ensuring cleanliness, dryness, absence of rust and oil stains to provide a good bonding foundation.
Use specialized high-performance adhesives. The tight bonding between polymer and metal can be achieved through molecular force, which is the key to ensuring that the polyurethane layer does not peel off.
3. Polyurethane formula and performance adjustment
The formula of polyurethane should be adjusted according to the specific usage conditions of the wheel, such as load capacity, speed, and environment. For example, polyurethane with different hardness is suitable for different scenarios, requiring a balance between wear resistance, impact resistance, and elasticity.
4. Process control
Material mixing: The mixing method and time should ensure that the materials are evenly mixed to avoid the formation of bubbles.
Sulfurization conditions: including temperature and time, require precise control to ensure that polyurethane elastomers achieve ideal physical properties

What are the benefits of using cast iron cores to produce 5 "x 2" Polyurethane on Cast Iron Wheel?
1. Reduce production costs
2. Has extremely high deformation resistance and wear resistance
3. The density of cast iron is higher than that of steel, which means that for the same size of wheel core, cast iron is heavier.
4. Cast iron has a low melting point, good fluidity, and low shrinkage rate, making it very suitable for casting wheel cores with complex shapes and precise dimensions. This makes it relatively easy to produce wheel cores with precise dimensions like 5x2 inches, and has a high yield rate.
