What are the methods for making plastic prototype samples?

Plastic prototypes, as the name suggests, are prototypes made using plastic materials. According to the production method, they can be divided into silicone mold prototypes, low-pressure casting prototypes, CNC prototypes, and 3D printed prototypes. Below, Kunshan Yushan Town Guanrui Prototype Model Factory, a plastic prototype processing manufacturer, has organized the following introduction for you:
1. Silicone Mold Prototypes
What is silicone molding? Silicone molding can produce many types of materials, such as PC and ABS, and soft rubber. Silicone molding, also called vacuum molding, requires a 3D printed or CNC machined model. Then, the original model is used to make a silicone mold, into which liquid material is poured. After the liquid material solidifies, the prototype model is formed.
2. Low-Pressure Casting Prototypes
What is low-pressure casting? Low-pressure casting, also called low-pressure reaction injection molding, involves mixing two-component polyurethane materials and injecting them into a rapid mold at room temperature and low pressure. Through chemical and physical processes such as polymerization, cross-linking, and curing, the product is formed. It has advantages of high efficiency, short production cycle, simple process, and low cost. It is mainly used for small batch trial production during product development, as well as small batch production of covers, uneven and varying wall thickness products. It has been widely applied in medical, technology, automotive, and other industries.
3. CNC Prototypes: This is a method of producing prototypes by carving and machining with CNC machines. It is the mainstream technology for prototype processing.
4. 3D Printed Prototypes: Currently, the most commonly used technology is SLA. Using 3D printers, it is convenient, fast, and inexpensive. Complex prototype models can be quickly produced. However, the strength and heat resistance are relatively poor, and the color may change over time.
