What are the advantages of high-speed cutting for injection mold processing

Injection mold processing is to add plastic into the mold first, and then the mold rotates along two vertical axes and heats it. Under the action of gravity and heat energy, the plastic in the mold is gradually evenly coated, melted and adhered to the entire surface of the mold cavity, molded into the desired shape, and then made by cooling and shaping. In the processing and production of injection molds, many injection mold factories will use high-speed cutting technology. What are the advantages of using high-speed cutting for injection mold processing?

In the process of high speed cutting, the tool and workpiece can maintain high temperature, which extends the tool life in many cases. On the other hand, in the use of high-speed cutting, the cutting amount is shallow, and the cutting time of the cutting edge is especially short. This means that the feeding time is faster than the heat transfer time.

Low cutting forces lose small and divergent tool bends. This, combined with the constant machining allowance required by each tool and process, is one of the prerequisites for efficient and safe machining.

Because the typical cutting depth in high-speed cutting of injection mold is shallow, the radial force on the tool and spindle is low. This increases the wear of the spindle bearing, guide rail and ball screw. High speed cutting and axial milling are also a good combination, which has little impact on the main shaft bearing. With this method, you can use a tool with a long overhang and have little risk of vibration.

High productivity cutting of small size parts, such as rough machining, semi finishing and finishing, has good economy when the total material removal rate is relatively low.

In this way, the clamping times of the injection mold processing are reduced. In addition, the geometric accuracy of the injection mold is improved through cutting. At the same time, the manual rest and the trial time can be increased. In addition, CAM and workshop oriented programming are used to help formulate process plans, and the application rate of machine tools and workshops is improved through process plans. Thus, the production cycle is greatly shortened and the production efficiency is improved, thus enhancing the market competitiveness of the injection mold factory.

High-speed cutting is a modern machining technology that has revolutionized injection mold processing. High-speed cutting uses advanced cutting tools and CNC machines to remove material at very high speeds and with great precision. Here are some advantages of high-speed cutting for injection mold processing:
  1. Faster processing times: High-speed cutting allows for faster processing times, as the machines can remove material at much higher speeds than traditional machining methods. This leads to faster turnaround times and increased production efficiency.
  2. Improved surface finish: High-speed cutting can produce a better surface finish on the mold, reducing the need for additional finishing operations. The smoother surface finish also helps to reduce friction and wear on the mold, leading to longer mold life.
  3. Increased accuracy: High-speed cutting machines are highly accurate, allowing for greater precision in mold production. This results in more consistent part quality and tighter tolerances, reducing the need for rework and improving overall efficiency.
  4. Reduced tool wear: The advanced cutting tools used in high-speed cutting are designed to last longer than traditional tools, reducing the need for frequent tool changes and minimizing downtime.
  5. Greater flexibility: High-speed cutting can be used to create complex shapes and features that would be difficult or impossible to produce with traditional machining methods. This makes high-speed cutting a highly flexible technology that can be used to produce a wide range of mold designs.
  6. Cost-effective: Although high-speed cutting requires a significant initial investment in equipment and training, it can be cost-effective over the long term due to its faster processing times, increased accuracy, and reduced tool wear.

In conclusion, high-speed cutting is a modern machining technology that offers many advantages for injection mold processing. It allows for faster processing times, improved surface finish, increased accuracy, reduced tool wear, greater flexibility, and cost-effectiveness. These benefits make high-speed cutting an attractive option for manufacturers looking to improve their mold production processes.
