Foundry Process

We use advanced shell core shooting machines capable of producing up to 45 kg resin-coated sand cores. Each core is coated with a zirconium-based layer for a smooth surface and excellent heat resistance. Every core is thoroughly inspected to ensure perfect shape, strength, and dimensional accuracy.

Each core is carefully inspected under precision lighting before assembly. The inlet, exhaust, and water jacket cores are accurately aligned and checked with gauges, then fitted precisely into the main core to ensure perfect finishing of the cylinder head’s internal surfaces.

This meticulous process prevents mismatches, enhances casting accuracy, and ensures smooth engine performance. Our 5,000 sq. ft. assembly area is brightly illuminated, allowing quick detection of even the smallest defects and guaranteeing consistent, high-quality results.

The raw materials are charged into the furnace according to defined standards and specifications. Each furnace has a melting capacity of 500 kg with a cycle time of approximately 40 minutes. Once the metal is melted, a sample coin is sent to the spectrometer laboratory for composition analysis and quality verification. Only after the sample meets the required chemical and quality standards is the molten metal approved for pouring.

During pouring, both temperature and metal flow are continuously monitored to ensure consistency and product integrity. The approved molten metal is then cast into molds following the specified parameters, ensuring that all standards for temperature, flow, and composition are strictly maintained throughout the entire process.

Our shot blasting machine removes sand, scale, and surface impurities from castings, giving them a clean and smooth finish. This process enhances the appearance, strength, and quality of every casting before final inspection and delivery.
