Plastic parts manufacturers prefer injection moulding as their production method, not only for its efficient production but also the versatile utilization. This article involves 10 advantages of injection moulding, which are the reasons why plastic injection moulding has become the most popular method for plastic parts mass production.
Advantages of Injection Moulding
1. High Efficiency & Fast Production
Plastic injection moulding process is quicker than other moulding methods, because injection molds which were designed according to the customer’s specifications, support the mass production of plastic parts. The moulding process is automatic. Once the designed mould was made in moulding process, the cycle of production is short, quick and efficient.
With this high production output rate, plastic injection moulding is high efficiency and fast production. Moulding speed usually has about 15-120 seconds as its cycle time. The short period between cycles allows moulding manufacturers to reduce the time of production and the cost of production, and increase revenue and profit margins.
2. Different Geometry/Shape Design
Moulding process provides a high pressure during plastic parts manufacturing, and with this pressure, plastic parts can be shaped easier no matter what kind of complex shape and detail parts design they have. Fundamental design elements should be considered at the parts design phase, otherwise, there may have some injection moulding defects which influence the quality of plastic parts. The injection mould design involves wall thickness, rib design, boss design, corner transitions, and weld lines and gate placement and properly placed vents.
3. Enhanced Strength
Moulding manufacturers may add some fillers into the injection moulds. With these fillers, the density of the plastic may have a reduction while when plastic being moulded, it helps in enhancing strength to the part after it has been molded.
As one of the advantages of injection moulding, enhanced strength allows injection moulding to produce strong and durable parts.
4. Cost Saving
Plastic injection moulding takes lots of machines and robotics to finish an automate process. The only operator control and manage these machine and robotics. This automatic process helps moulding manufactures reduce their labor cost.
One injection mould can produce lots of plastic parts, therefore, mould designers should have a correct design to avoid moulding defects. Short production cycle takes high production output rate, if the design of mould is suitable, plastic injection moulding machine will have high efficiency, fast production and great output, which will reduce production cost for moulding manufacturers.
In plastic injection moulding, manufacturers can choose different materials and colors for their parts, which shows the flexibility of injection moulding. As two main factors of injection moulding, material and color should be considered at the parts design phase. Experience plastic injection moulding maker can suggest the best material for you from a variety of resins according to your parts’ application.
The advantages of injection moulding support moulding manufacturers use different types of plastic simultaneously. Co-injection molding allows manufacturers to use not only one specific type of plastic in moulding process.
Using various coloring systems you can color your plastic parts. The coloring systems offer their unique properties, advantages, and disadvantages.
6. Reduce Wast
Mass production moulding may create a mount of waste. Therefore finding a moulding partner who has quality, sustainability, and optimal safety can help you improve the efficiency of production and reduce waste during moulding. Plastic moulding manufacturers have green manufacturing initiatives, with less waste, have become the reliable choice for their customers.
Generally speaking, mold design plays an important role in reducing waste. Injection moulding has high repeatability, once the mold was made, it can be used again and again. This feature allows injection moulding having a high usage rate of molds, which reduces the plastic waste.
Injection moulding manufacturers achieve designs within no more than 0.001 inches error range, which satisfy the customers who require tight injection moulding tolerances. With the advantages of injection moulding, manufacturers can create mass production for the parts of a precise instrument.
8. High Repeatability
Once you finished a scientific mould design, it can be used once and once again. The advantages of injection moulding can help manufacturers create a mass production even for precise part in high-end industry, such as medical industry, automotive industry.
Plastic injection moulded parts can provide lighter and more precise parts for the automotive industry. Nowadays, automotive manufacturers prefer lighter, high-strength, high quality, and well performance parts to replace metal components in automobile manufacturing.
Plastic injection molded parts are lighter and higher quality than metal components. Therefore, they are preferred by high-end industry manufacturers.
10. Automatic Production
Most of the plastic injection moulding takes automatic equipment for assembly production. This process only needs one operator to control the machine and reduced the cost of labor efficiently. With automatic production, the efficiency of injection moulding increased, then a high production output has been made.
Stebro has a fully automatic assembly product line, which will efficiently reduce the cost of labor and production. Strict monitoring ensures the high quality of molded parts.
11. Reduce Finishing Requirement
There often have smooth, complete plastic injection molded parts. The plastic injection moulding process usually has no other steps when the parts have ejected from capacities. The advantages of injection moulding parts reduce the finishing requirement of plastic injection moulding, and there is no other extra cost for molded parts.
12. Product/Part Consistency
Most of plastic injection molded components have a consistent process, which also has high repeatability to achieve a complex design with tight injection moulding tolerances. The advantages of injection moulding promise plastic injection moulding able to use in critical-use applications, such as the medical industry, automotive industry, etc.
Injection moulding can save your labor and production cost and also can reduce waste, all of these help moulding manufacturers save their budgets. Besides, injection moulding has high repeatability, it has high production output rate and high efficiency and suite with various shapes and complex designs. Moreover, it has no other steps when the parts have been finished by moulding machine.
These advantages of injection moulding are the reasons why most manufacturers choose plastic injection moulding. After reading this article, 10 advantages of injection moulding will also help you understand how to choose a reliable moulding partner for your injection moulding business.
