What is PU Moulding?
This is the process of moulding Polyurethane (PU) material into a desired shape by means of a mould or die. Polyurethane is a versatile polymer that is liquefied, semi-solid, or foam and PU moulding enables it to acquire the required shapes with specific characteristics like flexibility, durability, and resilience.
Common PU Moulding Methods
We are PU Moulding manufacturers in Pune and here are some of the common methods polyurethane moulding.
1. Open Casting
It is an easy and inexpensive process in which liquid polyurethane is emptied between an open mould and left to dry. Perfect in the small production runs and prototype.
2. Spin Casting/ Rotational Moulding
The polyurethane is put in a rotating mould in powdered form and it melts covering the inside area evenly. Ideal in the production of hollow smooth products.
3. Reaction Injection Moulding (RIM)
The two or more liquid components are combined and injected into a mould and reacted to create a robust, lightweight finished component. Fit in the automotive and industrial parts.
4. Over-Moulding
The material is moulded on top of another, with a soft PU coated over it to enhance grip, beauty, or functionality. Usually applied in consumer goods and equipment.
5. Continuous Feed Production
Foam Polyurethane foam is manufactured continuously so that in large scale, the production of consistent foam products is easily achieved.
6. Injection Moulding
High pressure is applied to a closed mould where the heated liquid polyurethane is injected into the mould where it solidifies into precise and detailed shapes. It is best suited to large volumes.
7. Compression Moulding
Polyurethane is then put in a mould in a pre-measured position and pressed on both sides until it forms a shape. Applied to durable and solid objects.
8. Blow Moulding
The shape of a hollow polyurethane preform is achieved by filling the hollow preform in a mould with air. It fits perfectly on hollow objects, such as containers and bottles.

Benefits of PU Moulding
We are PU Moulding manufacturers in Pune and here are some of the benefits of moulding.
High Durability: Polyurethane products are very robust and have good resistance to wear and tear and hence perform well even when used heavily.
Excellent Flexibility: PU is easy to shape into soft, elastic, or rigid materials and can be functionalized in a versatile and broad way to suit many different types of products and applications.
Precise Shapes: PU moulding allows the production of correct and detailed designs and smooth finishes, which make detailed and customised parts possible.
Shock Absorption: Polyurethane substances are good absorbers and offer a better cushioning and protection to sensitive or delicate objects.
Lightweight & Cost-Effective: PU components are tough but light in weight, which helps in lowering the material expense and transportation, is facilitated without affecting quality.
Applications of PU Moulding
As PU Moulding suppliers in Pune here are the various applications of where polyurethane moulding is used.
Automotive Parts: PU moulding is used in production of dashboards, seats, bumpers, fenders and shock absorbing parts, which provide cars with strength, comfort and reduced weight to improve fuel economy.
Bedding & Furniture: Polyurethane is formed into cushions, mattresses and underlays that offer flexible comfort, excellent support and extended life cycle of the product to furniture and bedding.
Building & Construction: PU has wide applications in thermal insulation, door and window seals and protective finishes to offer energy saving, weather protection and corrosion resistance to buildings and appliances.
Footwear: PU moulding is suitable for the production of lightweight, abrasion-resistant, and shock-absorbing shoe soles that also have good water resistance.
Medical & Healthcare Equipment: Polyurethane is used in the orthopaedic braces, prosthetics and other medical tools that offer comfort, flexibility and reliability of performance to the patients.

FAQ’s
Ans: PU moulding is a process where polyurethane components are blended together and formed in a mould, from which they harden into the intended part. The process can create soft, flexible, or rigid parts with accurate dimensions.
Ans: Yes, it is possible to use PU moulding outside, but they may need UV shelter or finishes if at risk by the sun and the weather.
Ans: Some types of PU can be made from recyclable or bio-based materials. However, regular PU is not fully biodegradable. Therefore, it is best to dispose of it properly and recycle it.
