Production Line:
Our SMC Manufacturing Process
We specialize in manufacturing high-quality products using SMC (Sheet Molding Compound) through hydraulic press molding technology. Our complete production workflow ensures precision, efficiency, and consistent quality.
Raw Material Sourcing: We procure premium SMC raw materials, selecting suppliers with reliable quality control to lay a solid foundation for finished products.
Hydraulic Press Molding: The core production step—raw materials are precisely placed into custom molds and pressed using advanced hydraulic machines, leveraging high pressure and controlled temperature to shape the base products.
Trimming & Grinding: After molding, professional technicians trim excess flash and grind edges to refine product dimensions, ensuring a smooth, burr-free surface that meets strict tolerance requirements.
Waste Management: We implement eco-friendly waste handling—scrap materials from trimming and grinding are systematically collected for recycling or proper disposal, adhering to environmental standards.
Packaging & Storage: Finished products undergo quality inspections before being carefully packaged to prevent damage during transportation. All qualified products are then stored in our warehouse, ready for immediate shipment.
