3 Need to Know About Plastic Molding
Plastic molding is considered as one of the most widely-accepted process of mass production. You may wonder what takes part during the manufacturing process. First, raw materials are fed into the machine and heated. After the raw materials are melted, it is injected into the mold cavities then allowed to cool and harden before ejected from the machine, checked for quality and shipped to the clients.
The same process can be applied to various raw materials like glass, metal, confections, elastomer and plastic. It is possible to manufacture so many things using this manufacturing process. In fact, you are already using some of the products that it can manufacture; quick release buckles, water bottles, food containers, car parts, kitchen appliances, mobile gadgets, toiletries, safety gear, military equipment, toys and even sports gear.
How Plastic Injection Molding Came To Be
We have John Wesley to thank for the first patented molding machine in 1872. This paved the way for a mechanized process of manufacturing simple things like buttons or hair combs. Then James Watson made an improvement to what John Wesley has made. With the introduction of gas assistance in the manufacturing process, mass production in a faster pace was now made possible. Aside from that, the improvement made way for various products with intricate designs to be mass produced.
Manufacturing Accessories and Machinery
There are several equipment used in the production of duraflex stealth plastic buckles or your favorite plastic products. These are the frequently used ones.
- Mold – These are used in shaping the product to be manufactured. They are mostly made from alloys, pre-hardened steel, hardened steel or aluminum. Each type of metal comes with their own set of advantages and disadvantages so you may want to sit down and talk with the manufacturer to determine what’s best for you. The other term for mold is die.
- Mold storage – After the manufacturing process, the mold needs to be stored in a secure place. This is where the mold storage comes in. In the mold storage, temperature and humidity is kept on a perfect level to make sure that the injection molding cavity will last for a very long time. This is the very reason why storing custom molds come at a price.
The Pros of the Process
Injection molding comes with numerous perks.
- Economical – We have the efficiency of the process to thank here. High quality products are mass produced at a very fast pace and in large quantities, leaving behind little to no waste at all!
- Ecological – As mentioned earlier, the process leaves little or no waste and this is something that the environment can benefit with.
- Excellent finished products – Time and time again, the process has proven to be very beneficial for both the manufacturers and clients because of the quality of products that is produced. They tend to be very durable. It is possible to increase the quality of products too. All that is needed to do is reinforce the existing raw materials with other raw materials.
