PROCESS OF GRAY IRON SAND CASTINGS

When your order starts mass production, it will proceed in the following process. It is summarized as mold making, gray iron smelting, pouring, cooling, cleaning, heat treatment, finishing, surface treatment, packaging, delivery, after-sales service. Kindly contact our sales manager, they will take you to visit the factory and explain in detail.

01
Mold Making

The production of casting molds is divided into three parts. First, we need to make a model according to the drawing of the part. This model needs to leave enough processing allowance (if necessary). Secondly, make sand cores and sand molds. Finally, place the sand core in a specific position of the sand mold and close the mold to complete the production of the casting.
02
Gray Iron Smelting

During the gray iron smelting process, attention should be paid to the mass fraction of carbon and silicon elements. Too high or too low will reduce the performance of gray iron. Gray iron is divided into pearlite gray iron, ferrite gray iron, pearlite-ferrite gray iron and inoculated cast iron according to its internal structure, and the smelting methods are different.
03
Pouring

The smelted gray iron needs to be poured into the mold cavity along the pouring gate at a specific temperature and speed. If the temperature is too low, oxide scale will be generated on the surface, and if it is poured into the casting, it will cause a defective casting. If the speed is too fast, the air in the mold cavity cannot be discharged in time, resulting in defective products. This will reduce production efficiency.
04
Cooling

The cooling rate of the casting has a great influence on the graphite morphology and distribution, and the matrix structure. Reasonable control of the cooling rate of the casting can control the performance of the gray iron casting. The cooling rate can be increased by optimizing the pouring and cooling system.
05
Cleaning

After the casting is fully cooled, it needs to be sanded, cut, and shot blasted to obtain a casting. Most of the sand in the sand casting process can be recycled to reduce costs.
06
Heat Treatment

Common heat treatment methods for gray iron castings include stress relief annealing to prevent deformation and cracks in castings, graphitization annealing to eliminate white structure, reduce hardness and improve cutting performance, and surface quenching to increase surface hardness and extend service life.
07
Finishing

Use machining to complete the processing of casting surface, interior, holes and tooth surface. The main processing methods are turning, milling, grinding, reaming, drilling and tapping.
08
Surface Treatment

Physical surface treatment includes polishing, brushing, sandblasting, hot dip plating, powder coating, etc. Chemical surface treatment includes electrophoresis, passivation, etc. Our supply chain can meet most of your surface treatment requirements.
09
Packaging

We support services like packaging materials, appearance design, printing, etc. You can contact our sales manager to inquire about the details.
10
Delivery

We support DDP, DDU, DES, DEQ, EXW and other delivery methods, and can ship worldwide. We have professional freight consulting services and can help you find a better freight company for free.
11
After Service

We will ensure various problems after the delivery of goods through high-quality after-sales service. And help you build a personal demand library such as warehouse management from HULK Metal to provide more personalized services.

GRAY IRON INTRODUCTION

Gray iron is the most widely used cast iron. Its main components are iron, carbon, silicon, manganese, sulfur and phosphorus. It has excellent casting properties. Here is our understanding of gray iron, including its meaning, its common grades and applications. Because of our full understanding of gray iron, we can better specify the perfect solution according to your requirements.

Gray Iron

Gray iron is called gray iron because its graphite structure is flaky and its fracture surface is gray. The carbon content of gray iron ranges from 2.7% to 4.0%. According to the matrix structure, gray iron can be divided into three types: ferrite, pearlite-ferrite, and pearlite. The most widely used one is pearlite gray iron. Gray cast iron has good casting performance, good vibration damping, good wear resistance, good cutting performance, and low notch sensitivity.
Gray Iron Grade & Applications

Ferritic gray cast iron HT100: Suitable for unimportant castings with small loads and no special requirements for friction and wear, such as protective covers, covers, oil pans, handwheels, brackets, base plates, heavy hammers, small handles, etc.

Ferritic-pearlitic gray cast iron HT150: Castings that bear medium loads, such as machine bases, brackets, boxes, tool holders, bed bodies, bearing seats, workbenches, pulleys, end covers, pump bodies, valve bodies, pipelines, flywheels, motor bases, etc.

Pearlitic gray cast iron HT200 and HT250: More important castings that bear large loads and require certain air tightness or corrosion resistance, such as cylinders, gears, machine bases, flywheels, bed bodies, cylinder blocks, cylinder liners, pistons, gear boxes, brake wheels, coupling discs, medium pressure valve bodies, etc.

Nodular cast iron HT300 and HT350: important castings that bear high loads, are wear-resistant and have high airtightness, such as the bed, base, frame of heavy machine tools, shearing machines, presses, automatic lathes, high-pressure hydraulic parts, piston rings, gears, cams, bushings with large forces, crankshafts, cylinder blocks, cylinder liners, cylinder heads of large engines, etc.
