Injection molding is a fairly versatile method for the production of plastic parts, which has many advantages over other methods of injection molding plastic parts. This method is not only simple and more reliable than others, but also quite effective. The main six advantages of this method are:
1. High performance/efficiency – fast production
There are several basic reasons why plastic injection molding is considered the most acceptable and effective form of injection molding. The process itself is quite fast compared to other methods, and the high productivity of the products makes it even more efficient and cost-effective. The speed of the process of course depends on the complexity and size of the mold, but the interval between each cycle is only about 15-120 seconds.
By reducing the cycle times of the injection molding process, this method allows the production of a large number of molds in a short period of time, while increasing revenues.
2. An integrated approach to the design of plastic parts
The method of injection molding plastic parts can be used to produce both rather complex parts and rather monotonous ones.
This method also allows the production of millions of identical parts. In order to optimize and increase the efficiency of high quality injection molding and to maximize the accuracy and quality of the part itself, it is necessary to consider the basic design elements and requirements for part design.
Part design must be as precise as possible to maximize the efficiency of the process required for high pressure casting. A properly designed part allows the element to be manufactured smoothly and with high precision. At the same time, without a detailed and calculated drawing of the part, you can make big and costly mistakes for the company.
Industry experts unanimously agree that in any part drawing and mold making, there are basic design elements that must be considered in order for the injection molding process (injection process) to work correctly. These elements include: wall thickness, shape side design, structural roundness on the surface of the part, corner transitions, weld lines and entry placements, and properly placed vents.
3. Gain
Reinforcement is one of the important factors to consider when designing a mold for an injection molded part. The designer needs to have information about whether the part should be flexible or rigid (solid). This is to adjust the integrating fixtures/shape plugs or corner fixtures. Understanding the purpose of the part, as well as in what environment it will be used, is also an important nuance.
Finding a balance between the parts of the shape drawings will determine the required strength (load, endurance, material resistance) and stability (hardness, strength, safety factor, etc.). Another important element for the manufacture of a part is the choice of material.
4. Flexibility – material and color
Choosing the right material and product color are the two main factors in the manufacture of a plastic part. Given the wide variety of both of these components, there are many variations of their combination.
Advances in the field of polymers have reached significant heights in recent years and have contributed to the development and invention of new polymers/resins.
To make sure you choose the right polymer, the following elements should be considered: impact force (impact resistance), tensile strength (tensile load), modulus of elasticity, heat absorption, and water absorption.
Polymers can be painted over using various coloring systems, each of which has its own characteristics, advantages and disadvantages.
It is also important to use a casting machine that has already been used to mold plastic products from various polymers, especially those that comply with FDA, RoHS, REACH and NSF standards.
5. Waste reduction
When choosing a partner for casting large parts, you should choose those companies that use green technologies in their activities. The latter ensures high quality, consistency and optimal security.
During the casting process, excess plastic is formed. When choosing partners, you should focus on those companies that use technologies for processing excess plastic. The most eco-friendly plastics manufacturers use state-of-the-art machinery and equipment to reduce waste, reduce shipping and packaging costs.
6. Lower labor costs
In the plastics industry, labor costs are generally low compared to other types of injection molding. Injection molding equipment typically works with stand-alone, automated tooling to streamline processes and ensure smooth production with minimal oversight. And the ability to produce parts at a high enough level with a high throughput contributes to the economy and efficiency of the process.
