With the development of the plastics industry, the application scope of plastic products is constantly expanding. Industrial plastics are also constantly improving in terms of strength. The amount of plastic products is gradually increasing. Plastic molds are tools that provide complete configuration and precise dimensions to plastic products and are matched with plastic molding machines in the plastic processing industry. Due to the variety of plastic types and processing methods, and the complexity and simplicity of plastic molding machines and plastic products, the types and structures of plastic molds are also varied. Here, we will introduce the precautions for plastic mold design.
Some users often only focus on product development and neglect communication with mold manufacturers in the early stage of product research and development. After the preliminary design scheme of the product is determined, there are the following three benefits to contacting the mold manufacturer in advance:
Ensure that the designed product has a good forming process and prevent the modification of the finalized design due to difficult machining of parts.
The mold manufacturer can make design preparations in advance to prevent insufficient consideration and affect the construction period.
To produce high-quality molds, the close cooperation between supply and demand is required to reduce costs and shorten the cycle.
There are many types of molds. Different types of molds should be selected for molding according to different requirements such as part materials, physical and chemical properties, mechanical strength, dimensional accuracy, surface roughness, service life, and economy.
Molds with high precision requirements need to use high-precision CNC machine tools for processing, and the mold material and forming process have strict requirements, and mold technology should be used for design and analysis.
Some parts require special requirements during molding, and the mold also needs to use processes such as hot runners, gas-assisted molding, and nitrogen cylinders.
Plastic mold production manufacturers should have CNC, EDM, wire cutting machine tools and CNC copy milling equipment, high-precision grinding machines, high-precision three-coordinate measuring instruments, computer design and related software.
Generally, large stamping molds (such as automobile cover molds) need to consider whether the machine tool has a flanging mechanism, multiple stations, and other factors besides stamping tons. In addition, the mold and machine tool protection devices should be considered.
Not every enterprise has the manufacturing methods and processes mentioned above for making molds. When choosing a manufacturer, you must understand its processing capabilities and not only look at the hardware equipment but also combine management level, processing experience, and technical strength.
The quotes from different plastic mold manufacturers for the same set of molds sometimes vary greatly. You should not pay fees higher than the value of the mold nor lower than the cost of the mold. Mold manufacturers, like you, need to make reasonable profits in their business. It will be troublesome to order a set of molds with a low price and many problems. Users must measure everything comprehensively based on their requirements.
