Vacuum duplication and low-pressure infusion are common methods of hand plate processing, the principle of the two looks more similar on the surface, through CNC machining or 3D printing to make the original, more complex structures can be made by low volume manufacturing3D printing to make the original, and then use the original to make silicone molds, and then the silicone molds can be copied in bulk, but in fact there are still some differences between the two, the following gives you an analysis of Vacuum mold and low-pressure infusion of two kinds of hand version of the difference between processing.
Vacuum Reproduction Mold
Vacuum re-mold is a common processing method, using the original template in a vacuum state to make silicone molds, and then pouring PU material in a vacuum state, so as to clone the exact same replica of the original template. custom part manufacturerIt is mainly used for small batch customization of plastic hand plates, generally dozens to hundreds of plastic hand plates. It is more cost-effective to handle in this way.
Vacuum re-molded products for material use performance can simulate the study of most enterprises existing system engineering construction material technical performance, common problems materials are domestic PU, imported PU, transparent PU, soft PU, race steel, ABS, PP, PC high temperature resistant ABS, etc., while transparent parts such as PC, plexiglass, etc., thermoplastic elastomer TPR, TPR, TPU, etc. and through a variety of soft materials such as silicone, rubber, etc. At the same time we can add students to replicate the company's products in a variety of different colors to meet the needs of society's various architectural appearance design. Products can be replicated without the volume, the degree of complex development, a variety of economic structure, etc., easy to open the mold, short cycle time, fast results.
Second, low-pressure infusion
Low-pressure injection molding, also known as low-pressure reactive injection molding, is a new technology applied to rapid molding, which mixes two-component polyurethane materials and then injects them into rapid molding at room temperature and low pressure. The products are formed through chemical and physical processes of materials such as polymerization, cross-linking and curing. prototype machining servicesThe utility model has high efficiency, short production cycle and low cost. It is suitable for small batch trial production in the product development process, small batch production of lids with simple structure, and production of products with large wall thickness unevenness.
Low Pressure Perfusion
Europe and the United States use the lowest infusion pressure and are more mature in terms of material and infusion technology. The first low-pressure infusion technology used in China was applicable to the automotive industry. In recent years, more and more low-pressure infusion technology has been used in the production of domestic medical devices, and because there are not many domestic medical device products, the sales volume of one product can reach tens or hundreds of sets each year. If you open a steel mold, the injection molding cost will be much higher. There are also many medical products with thick wall thickness, or uneven wall thickness, not suitable for injection molding, the surface surface is more complex, not suitable for bubbling process, but low-pressure infusion is different, you can pour thick-walled products, wall thickness can be uneven products, normal wall thickness (5-6mm) can be in the 30mm 🙂 The mold uses a large number of materials (aluminum profiles, resin molds, plastic molds, plaster molds, etc.) , and The choice of pouring material, there are imported materials, there are domestic materials, there are materials close to ABS, there are materials close to PP.
What are services for CNC machining?
By carefully choosing which materials to remove, CNC machining is a quick manufacturing method that converts digital 3D blueprints into plastic or metal objects. Many businesses use CNC machining services to create prototypes and parts, and many sectors employ flexible technology. But there are different types of CNC machining.

What is manufacturing with low volume and high mix?
Make-to-order manufacturing, also known as high-mix, low-volume (HMLV) production, is the process of producing a wide range of goods in modest numbers. This kind of production is frequently used to manage and produce complex, one-of-a-kind products that must meet strict quality standards.
