Hot Forged Steel InsertsHot-forged steel inserts are used for maximum strength, instead of cast-iron links, like with some aftermarket producers. We supply professionally iron core for rubber track by both forging and precoated sand casting with competitive prices and good services for many years. Mainly export to Japan, Poland, etc. Please mail your inquiry to or or call us 86-18132789710.

How to reduce casting defects on the raw casting components?

When machining the raw casting parts, some casting defects will be found, such as shrinkage, sand holes, segregation and other various defects, which will cause high reject rate. If melted down, it will take many manual power, material resources and financial resources, etc..So what can be done to reduce some casting defects? High-quality meltingBefore pouring, it is necessary to plan and check all smelting process. As per our customer’s requirements, our engineers will plan and adopt the suitable production plan. Avoid turbulent inclusions and control the flow rate.If using the closed pourcing system or producing the thin-walled casting components, the flow rate of the smelting steel or iron should be increased appropriately, which means that the drop height of metal liquid can not exceed the critical value of the static drop height. Avoid the air bubbles generated by the sand core or sand mold directly entering the liquid. The sand core must maintain a relatively low gas content, and can also be vented to reduce the generation of pores in the sand core. Or the sand core can be completely dried, otherwise the clay or the base sand core mold repair glue is used.

The Difference between cast aluminum alloy and die casting aluminum alloy.

Cast aluminum alloys are mostly the 300-series(Al-Si-Cu or Al-Si-Mg) alloys, such as 319, A383, A380, A360, 356, A356. But how to choose the most suitable aluminum alloys when producing aluminum alloy parts? Cast aluminum alloys mains the aluminum alloy casting components which produced by sand casting, gravity casting and other casting methods, such as A356, ZL101, ZL104, ZL102, etc Die Casting aluminum alloys mains the aluminum casted parts which manufactured by high pressure die casting process, such asA360, A380, A383, A518, ADC10, ADC12, etc Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. In China, you will find ZL can represent the cast aluminum alloy grade, YL means the die cast aluminum grade. By the way, the cast aluminum castings can be heat-treated, generally T6 heat treatment. But die casting parts are not suitable for T6 heat treatment because the temperature of T6 heat treatment is very high, lower than the melting point of aluminum alloy 15-20 degress, the gas in the die casting parts will expand ad be forced out of the casting surfaces, which will cause casting defects. So if you need aluminum alloy casting parts, aluminum die casting components, please feel free to contact Baoding Guokun via or or call us 86-18132789710.

How to reduce the shrinkage of steel casting components?

When making steel casting components, we will find some shrinkage, which will cause high defect rate. So how to reduce or avoid the shrinkage when lost wax casting process? Firstly, we should ensure the uniform wall thickness, usually not less than 8mm. Secondly, we should design the pouring temperature to around 1580°C. The temperature is higher, the molten steel’s fluidity is more better. But if too high, it also can cause other casting defects. By the way, the quartz sand is the best casting material under high temperature conditions. Lastly, Baoding Guokun use the suitable design of riser, cold iron, iron supplement to ensure the solidification to prevent casting defects, such as shrinkages. If you need casting components, steel casting parts, steel investment casting, please contact or or call us 86-18132789710.

The reasons and solutions of casting cracks.

When manufacturing steel casting components, so many casting defects will be occured if having incorrect or improperly casting operation, such as casting cracks. With more than 15 years of casting experiences, we made a summary of the reasons and remedies of casting cracks. The cause of cracks in steel castings are: The surface defects and internal defects will cause some cracks; The cooling rate is too fast during the cooling process; The stress relief was not performed in time after cooling the casting components; The cross section of castings changes too suddenly The transition’s corners are too small. How to prevent the cracks when casting? We need to improve the casting’s structure when designing; Improving the melting quality of casting alloy steel; Adopting the correct casting method and heat treatment process. Simultaneous solidification of castings not only helps prevent hot cracking, but also helps prevent cold cracking. Reasonably setting the position and size of pouring riser so that the cooling speed of each casting part is as uniform as possible to reduce the cold cracking; In short, when producing steel castings, we must be careful and meticulous in order to get a perfect finished products.
