Precision extrusion die
This set of Precision extrusion die is used for export to Singapore.The production speed is 6 meters per minute.The tolerance range of wall thickness is ±0.1mm, and the tolerance range of length and size is ±0.5mm. If you need a similar mold, we can meet your requirements through special technology.
To achieve Precision extrusion die, technical support needs to be provided from the following aspects:
1. Design of the head: Ordinary clothes hanger type flow channels should not be used. The drawback of the clothes hanger type flow channel is that changing the raw materials and formulas can cause the outflow to be out of sync, and different screw structures and screw rotation speeds can also cause the outflow to be out of sync. External factors are difficult to be absolutely the same, so using the clothes hanger type flow channel makes it difficult for the Precision extrusion die to maintain synchronous outflow. The head structure must adopt a mesh-type feeding method, which ensures stable feeding, stable pressure, and the outflow stability is greatly affected by external factors. The disadvantage of the mesh-type feeding method is that the processing technology is complex and the cost is high, but it can ensure that the tolerances at all positions are within ±0.1mm.
2. For this type of cross-section, a speed of 6 meters per minute is a relatively high speed. There are two design schemes for the calibrator. Scheme one: The calibrator material uses copper, which has good thermal conductivity and can quickly remove heat, quickly shape, and the production speed is naturally very high, but the Precision extrusion die cost is very high. Scheme two: Use normal mold steel, and the first section of the calibrator adopts vacuum cooling and adsorption shaping, and the bottom uses direct cooling water spraying onto the surface of the profile. This design concept can also quickly remove heat, but the disadvantage is that it requires an experienced operation engineer, and the size of vacuum and water spraying needs to be adjusted. If using our AONA TOOLING company’s molds, there will be a set of adjustment instructions with the EXTRUSION mold, allowing your company to minimize the reliance on technical workers.
3. Consistent flow of raw materials for each batch, and a reasonable formula are also important factors to ensure stable production.
