General Stamping

After punching section about 20% of the cut surface, 80% of the tear surface, the advantage of low cost, high speed, suitable for simple shapes, less precision machining.

Precision Cutting

Design approach is to use a special machine with a V-shaped ring, the gap through rational selection, convex, cracks material overlap at the die edge, and to avoid the process of punching in the material flow, resulting in tearing or Second generation punching circumstances, to achieve 100% bright shear plane. 1. The advantage is better flatness 2. higher precision, dimensionally stable 3. 100% cut surface is smooth, no need for further processing grinding, eliminating rework costs & time for high precision machining or molding complex and difficult process time.

Heat Treatment

Based on material properties, select "General heat treatment" or "vacuum heat treatment", the biggest difference between the two lies in the supply of oxygen.

Heat treatment is generally placed in the steel is heated to the desired temperature in air transport tunnel, its advantage lies in lower production costs and higher productivity; vacuum heat treatment is to remove the oxygen in a sealed vacuum furnace operating environment, and its advantage is better strengthen the grain structure of the workpiece to obtain a more stable and higher hardness.

Heat treatment is the use of prolonged heating at high temperature, so that the chemical composition of the interior is sufficiently diffused, to strengthen the hardness of steel, the cutting action and wear resistance, and eliminates internal stresses, improve toughness and ductility. The heating temperature will vary due to the steel material, usually between 1200°C to 1300°C homogenized, high carbon between 1100°C to 1200°C, and general forging or rolling of steel at 1000°C to 1200 This heat treatment is carried out between °C.

Surface Grinding

Specifications using different abrasive grinding wheel, the workpiece can be removed by heat treatment of the decarburized layer, but also allows the workpiece to a suitable processing size and roughness.

Abdominal Grinding

By grinding wheel or belt processing methods, the workpiece into classes arc, is intended to enable the workpiece two scissors minimize the contact area, reducing the shear friction coefficient, increasing shear life.

Oblique Grinding

Use wheel cutting function, scissors shear plane processing to the appropriate angle to achieve a balance of shear capacity and shear life.

Large angle of the shear plane for heavy cutting or large piece of shear force, the advantage of easy to damage.

Small-angle shear plane applicable light cutting or shearing forces in the small of the workpiece, the advantage lies in favor of cutting.

Buried Shot

The metal parts (blade) into the injection mold injection combined do.

Advantage lies buried artifacts and plastic injection combined degree of good, the disadvantage is that the cost of production than the average unit price shot high.

Monochrome shot fired into a single feed, mixing with a single shot fired materials such as multi-color; generally powered by a single shot fired mainly monochrome material.

Surface Treatment

Using a variety of painting, stamping, plating, deposition, PVD.. way to make different patterns, patterns of treatment on the workpiece.
