Liberal Mould specialises in composite mould and injection mould, we are capable of providing a one-off solution for our customers from mould development, design, and mould making to finished products according to our customer requirements.
Sheet Moulding Compound (SMC) technology is a versatile and advanced process used in the production of high-strength, durable, and lightweight components. SMC involves the use of pre-impregnated fibre-reinforced resin sheets that are moulded under heat and pressure. This process results in products with mechanical properties, nice resistance to environmental factors, and a high degree of dimensional stability. SMC manhole covers benefit from these properties, making them ideal for various applications in infrastructure and construction.
Advantages of SMC Manhole Covers
Durability and Strength: SMC manhole covers are renowned for their robustness and resistance to heavy loads. The composite material used in these covers can withstand significant stress and strain, making them suitable for high-traffic areas and harsh environmental conditions.
Corrosion Resistance: Unlike traditional metal manhole covers, SMC manhole covers are highly resistant to corrosion and chemical attacks. This property ensures a longer lifespan and reduces maintenance costs, making them a cost-effective choice in the long run.
Lightweight: One of the key benefits of SMC manhole covers is their lightweight nature. This feature facilitates easier handling and installation compared to traditional heavy metal covers, reducing labor costs and simplifying maintenance procedures.
Design Flexibility: The SMC moulding process allows for a high degree of design flexibility. This means that manhole covers can be manufactured in various shapes, sizes, and styles to meet specific design requirements and aesthetic preferences.
Comprehensive Mould Development Process
Initial Consultation and Design: Our process begins with a thorough consultation to understand our client’s specific needs and requirements. Our design team works closely with clients to develop detailed specifications and 3D models of the manhole cover, ensuring that every aspect of the design meets the desired performance criteria.
Prototype and Testing: Once the design is finalized, we create a prototype of the SMC manhole cover using our advanced moulding technology. The prototype undergoes rigorous testing to evaluate its performance under various conditions. This step is crucial to ensure that the final product will meet all necessary standards and regulations.
Mould Manufacturing: With the prototype approved, we proceed to the mould manufacturing phase. Our skilled engineers use advanced techniques and high-quality materials to produce precision moulds that ensure consistent and accurate production of manhole covers.
Production and Quality Control: The moulds are used to produce the final SMC manhole covers. Each cover undergoes stringent quality control checks to ensure that it meets our high standards for durability, strength, and dimensional accuracy. Our quality assurance team monitors every stage of production to maintain high level of quality.
Customisation and Client Support
Tailored Solutions: We offer tailored solutions to meet the unique needs of each client. Whether you require manhole covers with specific load-bearing capacities, custom designs, or special features, our team is equipped to deliver products that align with your specifications.
Ongoing Support: Our commitment to client satisfaction extends beyond the initial sale. We provide ongoing support and maintenance services to address any issues that may arise and ensure that our products continue to perform at their good throughout their lifespan.
Environmental Considerations
Sustainability: SMC technology is environmentally friendly, as it reduces the need for heavy metals and reduces waste during the manufacturing process. By choosing SMC manhole covers, clients contribute to sustainable construction practices and reduce their environmental footprint.
