Benefits of Custom cold forging/cold heading
Most of machined parts could be re-designed and re-manufactured to be parts made by technology of cold heading,which help you to get significant cost savings.
Improve production effience and reduced Production costs:Because of using high speed manufacturing process. The speed reaches range from 10 pieces per minute for low volume large press work to to 450 pieces per minute on the cold heading process.
Save material cost: Compared to a traditional machining process, cold forming process can save up to 70%.
Better control product tolerance: compared to more expensive machining processes,less tolerance can be achieved throughout the production process by coldforming
Higher and better quality surface: compared to conventional machined surfaces ,cold forming process can get result . The cold forming process can eliminate the need for costly secondary operations, such as welding, machining, etc, with careful product and process design,
Improved part performance and characteristics: due to the metal deformation resulting in improved grain structure, while work hardening can yield significantly improved product performance,cold forming process can improve metal part performance and its characteristics.
See how the technology of cold forging/cold heading to save materials cost:
Advantages of cold heading
Speed
Depending upon the size and complexity of the part and the nature of the equipment of producing them, production rates of 4000 pieces per hour can be achieved.
Economy
When compared to casting and machining labor the metal savings alone justify the conversion to an impact extrusion.In some cases when the aluminum slug is sized accurately, little or no trimming or other secondary operations are required.
Strength
The impact process naturally work hardens non-heat treatable alloys, while the heat treatable alloys can be heat treated in normal fashion after processing.
Toughness
The impact extruding process produces parts that are dense and porous-free in structure. This condition cannot be obtained in a casting process or by machining of a bar material.
Versatility
After impacting, the product can be treated the same as any other piece of material. Secondary operations such as machining, grinding, welding, bending, plating or anodizing can be performed in the same way as any other piece manufactured by a more conventional process.
Consolidation
Impacts can directly replace machined components, or welded or riveted assemblies, in many designs. The process often reduces product costs for secondary machining operations and in many cases increases the strength of a product that was previously an assembly.
General knowledge on “metal nuts” ?
Nut, always used with bolt or screw together to play the role of fastening, is a must-have component of all manufacturing machinery. According to the different materials,it can be made from carbon steel, stainless steel, copper, alloys, etc. According to the shape,it can be divided into: self-locking nuts, pine nuts, lock nuts, four claws nut, screw nut insurance nut, thin rod screwed self-locking hex nut cap nut dedicated ground screw nut, hexagon-shaped thin crown nut nut rings. Fine tooth Full Metal hex flange locknuts, all-metal hexagon nuts with flange, fine tooth non-metallic insert hex nuts with flange, small teeth hex flange nuts, weld nuts square, hexagonal welding nuts, fastening nut, fitted round nuts, slotted round nuts, nut side with hole circle, end with a hole circle nuts, small round nut round nut, the ring nut, wing nut.
Surface treatment: zinc plating color and white zinc plated, usually cold galvanized!
Applications: Automobile industry – cars, trucks, buses, compressors, construction machinery, wind power equipment, agricultural machinery, fasteners, foundry industry, drilling equipment, shipbuilding industry, military, mining equipment Oil drilling rigs (onshore or offshore), utilities, rail transportation, transmission, metallurgical equipment
Nut quality detection and checking
Bolt detected ways can be divided into labor detecting and machine automatic detecting. Labor is the most original and most widely used way of coincidence detection. In order to minimize the outflow of defective products, the general production of corporate officers by visual approach to packaging or shipment of product testing to rule out defective products (including bad teeth hurt, mixing, rust, etc.). Another way for automatic testing machine, mainly magnetic particle inspection. Magnetic particle testing is the use of the leakage magnetic field interacting with the magnetic particle defects of the bolt, bolt for possible defects (such as cracks, slag, mixing, etc.) differences in permeability and permeability of the steel, after magnetization of these materials are not continuous Kawasaki will occur at magnetic field changes, the magnetic flux leakage portion is formed at the surface of the leakage magnetic field generated in order to attract magnetic particles to form a magnetic powder defect accumulation – magnetic marks, under appropriate lighting conditions, showing the location and shape of the defect, for accumulation of these magnetic powder to be observed and interpreted, has reached the purpose of removing defective products.
