What are the advantages and disadvantages of 3D printing processing compared with injection mold?
What are the advantages and disadvantages of 3D printing processing compared with injection mold? Let's learn about the Qile Script:
Introduction to injection molding: It is one of the most commonly used manufacturing processes for mass production of plastic parts. Use the movable plunger to inject the hot material into the mold through the nozzle. The material fills the mold and then cools.
Process flow: mold closing ->injection ->pressure holding ->cooling ->mold opening ->product removal
Advantages of injection molding:
High production efficiency
Various materials can be processed
No surface processing required
Low labor cost
5. Fully automated
Disadvantages of injection molding:
High initial investment/expensive equipment
High mold cost
High start-up and operation costs
4. Component design limitations
Introduction to 3D printing technology: 3D printing is a kind of rapid prototyping technology, which is also called additive manufacturing. Its basic principle is to cut a 3D model made by design or scanning into an infinite number of sections according to a certain coordinate axis, and then print it layer by layer and stack it together according to the original position to form a solid solid model.
Process flow: construction of 3D model of product ->generation of print model format ->slicing of 3D model ->molding ->post-processing of parts
Advantages of 3D printing:
No cost increase for manufacturing complex items
Product diversification does not increase costs
No assembly required
Zero time delivery
Space free, portable manufacturing
Unlimited design space
Infinite combination of materials
Zero skill manufacturing
Reduce waste by-products
10. Accurate solid copy
Disadvantages of 3D printing:
1. The cost is high and the manufacturing efficiency is not high, so it is not suitable for mass production at present.
2. At present, there are some restrictions on printing materials, mainly including various engineering plastics, some metal materials, gypsum, ceramics, etc.
3. Precision and quality problems. At present, the precision, physical properties and chemical properties of 3D printing molded parts can not meet the practical application requirements of the project. They can only be used as prototype parts, not as functional parts.
The above is a comparison between 3D printing technology and injection mold. In general, 3D printing has broken through the old familiar traditional manufacturing limitations and provided a stage for future innovation. At this stage, the 3D printing process is best at printing parts rather than molds. However, 3D printing injection mold is a reliable alternative when conditions are met.
