1, stainless steel, the main use of no surface treatment, high cost.
2, hot-rolled plate SHCC, material T ≥ 3.0mm, but also with electroplating, paint pieces, low cost, but difficult to form, mainly with flat parts.
3, galvanized sheet SECC, SGCC. SECC electrolytic plate sub-N material, P material, N material is not the main surface treatment, high cost, P material for spraying.
4, copper; the main use of conductive materials, the surface treatment is nickel, chrome, or not for processing, high cost.
5, aluminum; general use of surface chromate (J11-A), Suzhou laser sheet metal processing oxidation (conductive oxidation, chemical oxidation), high cost, silver, nickel.
6, aluminum; cross-sectional structure of complex materials, a large number of used in a variety of boxes. Surface treatment with aluminum.
7, cold-rolled plate SPCC, mainly with electroplating and paint pieces, low cost, easy to shape, material thickness ≤ 3.2mm. The general sheet metal processing bending plate 90 degrees are required in the V-shaped planing through the pressure to achieve, so they are the relationship between the tooling tool v-type grouting processing can also be said to be a sheet metal processing a process, and some sheet Gold products (thick thickness) after bending the outer R angle is too beautiful, sheet metal processing so at the bend at the v-groove (that is, the thickness of the thin planing), V-shaped planing has two roles: a Is to reduce the bending angle, the general sheet metal bending angle is equal to the thickness of the floor, if the workpiece requirements of the bending angle is less than the thickness of the floor, the need to plan V-groove; the second is to reduce the bending force Suzhou sheet metal Processing plant, when the workpiece bending force is greater than the tonnage of the bending machine and can not bend, you can plan V-groove to reduce the bending force.
1, cutting: cutting a variety of ways, mainly in the following ways
①, punch: the use of punch or more step or more steps in the plate after the expansion of the flat parts of the plate forming a variety of shapes and pieces of materials, the advantages of short labor costs, high efficiency, high precision, low cost, Production, but to design mold.
②, shear bed: the use of shear bed shear strip material simple material, it is mainly for the blank blanking material preparation processing, low cost, accuracy less than 0.2, but can only be processed without holes without cutting the strip or block material.
③, laser cutting, is the use of laser cutting, cutting the flat plate in the shape of its structure cut out, with the NC cutting the same need to write a laser program, it can be under a variety of complex shape of the plate, high cost, At 0.1.
④ NC NC cutting, NC cutting the first time to write CNC machining program, the use of programming software, the drawing will be compiled into NC number drawing machine can identify the program, so that according to these programs step by step Suzhou sheet metal processing Flatten the flat plate on the plate shape, but its structure by the tool structure to the low cost, accuracy of 0.15.
⑤, Saw: the main use of aluminum, square tube, tube, round bar and the like, low cost, accuracy.
In a large number of sheet metal processing, the installation of sheet metal cabinets is very important, and its production process requirements are also very strict, which is the export of goods packaging containers are required to do performance testing, inspection, "export goods transport packaging inspection Application form ", the production unit of the batch of packaging containers to test the results of single, packaging containers specifications list, customer orders and packaging containers of the requirements of Suzhou sheet metal processing, the packaging of the packaging design process, materials, testing standards and other technical information.
