Innovative application of gas assisted injection molds in consumer electronics

1, Optimization of production workshop layout
Optimizing the layout of the production workshop is the first step in achieving energy efficiency optimization. The layout of the production workshop should consider two aspects: one is to meet production needs and ensure smooth production processes; The second is to meet the flexible energy requirements under specific production conditions. Specifically, the following measures can be taken:
Power supply optimization: While meeting the power requirements for stable production, it is necessary to ensure an appropriate margin in the power supply system to avoid excessive consumption of non functional power due to excessive margin.
Cooling water circulation facilities: Construct efficient cooling water circulation facilities and equip the cooling water system with effective insulation and thermal insulation systems to reduce energy loss.
Optimize production layout: Optimize workshop layout based on production processes, arrange processes reasonably, and reduce turnover time and energy consumption.
Lighting control: The most effective small units are used to control lighting and other factory equipment separately, and adjustments are made according to actual needs to reduce unnecessary energy consumption.
2, Selection and maintenance of injection molding machines
The injection molding machine is the main energy consuming equipment in the injection molding workshop, and its energy consumption is mainly concentrated in the motor and heating system. Optimizing the selection and maintenance of injection molding machines is crucial for reducing energy consumption.
Choose the appropriate injection molding machine: Choose the appropriate injection molding machine based on the characteristics of the product to avoid energy waste caused by the "big horse pulling small car" style. For different types of electronic products, injection molding machines that match their production needs should be selected.
Adopting energy-saving injection molding machines: Fully electric injection molding machines and hybrid injection molding machines have excellent energy-saving effects and can significantly reduce energy consumption. Compared with traditional mechanical hydraulic injection molding machines, these new injection molding machines have higher energy efficiency ratios.
Heating technology innovation: Adopting new heating technologies such as electromagnetic induction heating and infrared heating can improve heating efficiency and reduce energy loss.

CAE assisted design: Using CAE assisted design technology for mold design, mold flow analysis, and simulation can reduce energy consumption for mold debugging and multiple mold repairs.
4, Peripheral equipment configuration
The configuration of peripheral devices is also an important factor affecting the energy consumption of injection molding. Reasonable selection and configuration of peripheral equipment can further improve production efficiency and energy consumption levels.
Select auxiliary equipment that is suitable for the job requirements: On the premise of meeting the job requirements, choose auxiliary equipment with appropriate capabilities to avoid energy waste caused by excessive surplus.
Equipment maintenance: Regularly maintain and upkeep peripheral equipment to ensure that it is in normal working condition. Auxiliary equipment that is not functioning properly can cause production instability, even leading to poor quality of parts and increased energy consumption.
Optimize equipment coordination: Optimize the coordination and operation sequence between the host and peripheral devices to reduce energy consumption. At the same time, optimize the mutual position between peripheral devices and production equipment, and make peripheral devices as close as possible to the host without affecting operation.
5, Material Management
The selection and management of materials also have a significant impact on injection molding energy consumption. Reasonable selection and management of materials can further reduce energy consumption.
Preferred low-energy materials: prioritize materials with lower processing energy consumption while meeting product performance requirements. At the same time, prioritize the selection of high liquidity materials while meeting the conditions of performance and cost optimization.
Material drying treatment: When drying materials, it is best to use them as they dry to avoid energy waste caused by moisture regain after drying.
Material preservation: Properly preserve materials to prevent impurities or foreign objects from entering, ultimately leading to product defects and increased energy consumption.
6, Optimization of processing technology
The optimization of processing technology is also an important means to reduce injection molding energy consumption. By optimizing the processing technology, production efficiency and product quality can be further improved while reducing energy consumption.
Shorten molding cycle: Using the shortest molding cycle while meeting product performance requirements to reduce energy consumption.
Use recommended processing techniques: If there are no special factors affecting it, try to use the processing techniques recommended by the supplier as much as possible to ensure stable product quality and reduce energy consumption.
Optimize process parameters: For specific products and molds, save all stable equipment and process parameters for quick machine adjustment during the next production change, reducing energy consumption.
7, Application of New Technologies
With the development of technology, the application of new technologies in the field of injection molding is becoming increasingly widespread. The adoption of new technologies can significantly improve production efficiency and product quality, while reducing energy consumption.
Auxiliary molding technology: using gas assisted, liquid assisted, steam assisted, micro foaming injection molding technology and other auxiliary molding technologies can shorten the molding cycle and reduce energy consumption.
Unit forming scheme: Adopting a unit forming scheme, reducing intermediate links, improving production efficiency, and reducing energy consumption.
