The precision of concentricity is less than 0.001 MM and the accuracy of true roundness is less than 0.001 MM. Effectively reduce the cumulative tolerance of the whole set of dies and ensure the concentricity of products within the requirements.

　　Ultra-precision precise positioning with concentricity accuracy less than 0.0005 MM and true roundness accuracy less than 0.0005 MM. Effectively reduce the cumulative tolerance of the whole set of dies and ensure the concentricity of products within the requirements.

　　Thickening the bottom plate of the die surface of larger products can reduce the force of the AB template, reduce the deformation of the AB template, and ensure the flatness of the whole plate.

　　Small products are processed by integral die, rubber level is all processed by ultra-precision turning for bushing, ensuring accuracy within 0.001MM.

　　The water is transported on the tap, which can effectively reduce the heat transferred by the gun nozzle, reduce the injection cycle and reduce the cost.

　　AB template uses circular water transportation, around the die, so that the temperature is more uniform, to achieve constant temperature effect, to ensure the efficient and stable production of the die.

　　The pressure reducing groove is added to the bottom plate of the surface, so that the force of the whole set of moulds is more concentrated in the middle to ensure the stability of injection moulding.

　　The ejector pin panel is fixed on B plate by adding contour screw. When the die is loaded, the die core is installed, the contour screw is tightened, and the reset spring of the face needle plate is pressed first, then the ejector pin and the ejector rod are loaded. When removing the mould, the equal height screw is used to press the spring first, which effectively ensures that the mould kernel does not follow the ejector rod and avoids scratching.
