The Cause Of Uneven Wall Thickness During The Processing Of Rotomolded Products In the process of rotational molding, it is not easy to process plastic products with sudden wall thickness. The average wall thickness of the products depends mainly on the amount of material to be fed. The uniformity of the mold and the structure…
DetailsSolution To Uneven Wall Thickness During Processing Of Rotomolded Products The solution: 1. Fix the rotomolding mold to the appropriate position on the mold base and adjust the balance of the mold base. 2. The rotation speed of the main and auxiliary shafts is kept balanced and the speed is uniform. 3. The heating furnace…
DetailsProducts Appear Insufficient Melt Glue In The Injection Molding? When such problems occur, it is necessary to observe the movement stroke of the screw of the injection molding machine while injection molding. Pay special attention to the position of the screw when the pressure is completed and when the glue is completed. In the first…
DetailsThe Importance Of Effective Cutting Speed Since the table feed depends on the speed at a certain cutting speed, if the effective speed is not calculated, the table feed will be calculated incorrectly. If the tool’s nominal diameter value (Dc) is used in calculating the cutting speed, the effective or actual cutting speed is much…
DetailsMilling Cutter Positioning The cutting length is affected by the position of the milling cutter. Tool life is often related to the length of cutting that the cutting edge must bear. The milling cutter positioned in the center of the workpiece has a short cutting length. If the milling cutter is offset from the center…
DetailsUse Of Down Milling And Up Milling The main recommendation is to use as much milling as possible. When the cutting edge is just cutting, the chip thickness can reach its maximum value in the down-cut milling. In the case of up-cut milling, it is the minimum value. In general, tool life in up-cut milling…
DetailsWhat Is The Most Important Factor In The Cutting Process? One of the most important goals in the cutting process is to create an evenly distributed machining allowance for each tool in each process. This means that tools of different diameters (from large to small) must be used, especially in roughing and semi-finishing operations. The…
DetailsWhat Is The Most Important And Decisive Factor In Choosing Mold Steel? The cutting process should be divided into at least 3 process types: Roughing, semi-finishing and finishing, and sometimes even super finishing (mostly high-speed cutting applications). The residual milling is prepared for finishing after the semi-finishing process. It is important to work hard in…
DetailsWhat Are The Important Application Parameters For Hardened Die Steel Milling? When finishing high-speed milling of hardened die steel, one of the main factors to be observed is shallow cutting. The depth of cut should not exceed 0.2/0.2mm (ap/ae: axial depth of cut / radial depth of cut). This is to avoid excessive bending of…
DetailsWhat Is The Most Important And Decisive Factor In Choosing Mold Steel? 1. Forming method. Choose from two basic material types. (1) Hot working tool steel that can withstand relatively high temperatures during die casting, forging and extrusion. (2) Cold-worked tool steel for blanking and shearing, cold forming, cold extrusion, cold forging and powder press…
