The first automobile factory construction and its casting technology level. The first automobile factory started construction in 1953, and the first furnace hot metal was cast on March 26, 1956, declaring that China’s first large-scale production workshop for automobile castings was completed and put into production, setting a good example for the comprehensive development of China’s automobile industry’s casting production. . The foundry's material preparation, sand processing, molding and core formation, metal melting and casting, sand casting, cooling and cleaning of the castings are all through the mold conveyor, suspension chain, scale conveyor, and belt conveyor. And bucket elevators and other transportation equipment are combined into a whole. The balance wheel sand mixer, crawler type semi-automatic shot blasting drum, continuous hanging chain shot blasting chamber, cupola furnace and electric furnace double smelting, lift type electric annealing furnace and other process equipment all have the overseas 40s and 50s. Early technology level.
A large number of mechanized transport equipment will connect all processes into a complete production line. At the time, the model was a pneumatically-actuated or shock-pressure molding machine that was commonly used in the world, and six mechanized modeling flow production lines were formed by continuous or intermittent trolley-type casting conveyors. They were used for the molding of grey cast iron parts and malleable cast iron parts, respectively. The sand is sent by the belt conveyor from the sand processing department and stored in the sand bucket above the molding machine. The core of the production line is manually lowered. For the complex core groups used in the cylinder block and cylinder head, etc., they are pre-assembled, and then the cores are removed by air lifting jigs and manually boxed. The core is made of oil sand, pulp sand, and fat sand core. The core sand is made by the è¾— wheel type sand mixer; the small oil sand core is made by hand, and the large sand core is produced by the core making machine; the sand core is dried by the chain plate vertical continuous gas drying furnace.
Advantages of round pin fin Heatsinks:
First of all, the cooling efficiency is generated largely due to the unique design by which the round pin spread facilitates the fanning out of the Heatsink Fins within given space environment. Functioning best in an unspecified, omni- or multidirectional ventilation environment, the round pin fin heatsinks technology boasts dramatically increased cooling effects when compared with the normal flat pin fin heatsinks design.
Second, there is one more advantage of pin fin heatsinks, that is, it could be very small. Therefore, it is more appropriate to use it in products with high-added value and limited space.
Method of making round pin fin heatsinks:
Round pin fin Heatsinks can be manufactured from both Aluminum, and copper by various methods. The most efficient round pin fin heatsinks are forged that allows for both high aspect ratio designs, and also highly conductive materials to optimize this heatsink for highly demanding thermal environments.
we Suprel offer a wide range of copper and aluminum round pin fin heatsinks, both standard and custom heatsink designs.
