Sinotech Ltd

Sinotech Ltd aim to provide Cold Formed Parts: * Low cost to Manufacturers * Made to Customers Specification * Supplied by Chain Specialists for Automotive Supply * Many years experience with an Asian Source Sinotech, experts in coldforming components, have extensive experience in: * Net-shape coldforming * Near net-shape cold forming Sinotech is a supplier of precision components within the Automotive, Fluid Power and General Engineering Industries. We manufacture ISO 9001:2008 quality assured precision machined components, which can be produced using a number of processes: * Single spindle Low Volume components * Multi-spindle High Volume production * CNC turning utilising our multi axis technology * CNC milling utilising our 4 axis machining centres * Welded assemblies Sinotech can supply precision machined components in a vast range of materials including: * Copper * Mild and Alloy Steels * Titanium and exotic high temperature alloys * Plastics * Stainless Steel * Brass * Phosphor Bronze (Gun-metal) * Aluminium Die Castings - The molten metal needs to be injected into a mould under extreme pressure. This will result in a more homogeneous part, good surface finish and dimensional accuracy. There would be a significant reduction in the requirement for post casting processing to get the required final configuration. There are 5 main steps to the process cycle, these are: * Clamping - two cleaned and lubricated die halves are clamped together within the production machine * Injection - of molten metal (a pre-determined volume) at high pressure into the die * Cooling - The solidification of the metal within the die cavity takes its final shape * Ejection - From the die cavity, of the casting * Trimming - Excess material from casting Sintered Components Applications - Components produced by this route include the production of many complex components such as: * Pressure Plates * Gears * Cams * Sprockets * Levers * Ratchets * Bushing etc These would be used in the following industries: * Automobile * Hydraulic * Agriculture Pressings - Sinotech are able to work with their customers and use their extensive knowledge and experience of metal forming and tool design. To get the optimised final tooling design, prototype components can be produced. We are also able to supply Metal Stampings in a range of materials: * Steels, coated and uncoated * Stainless Steels * Aluminium * Brass
