Advantages of Plastic Injection Mold


Most of the products we use today, especially the components of large products, are manufactured using a process known as injection molding. Requires the use of mold cavities in which molten materials are poured and solidified to form everything from ice cream bowls and chairs to bottle caps and containers. Various materials such as glass, metal, and thermoplastic materials are used in injection molding. We'll see till the last one and how it stands out from the others in terms of cost and recyclability.


As we know, plastic is an inexpensive alternative to expensive metals and glass. It is durable, rustproof and surprisingly strong given its low density. Thermoplastic materials, in particular, enable low volume plastic molding manufacturers to produce highly complex shapes at significantly lower costs than other materials. It is flexible, which means that it can take almost any shape, but hardens on cooling. Additives are added to reduce brittleness when plastic is exposed to very cold temperatures. In addition, the finished products can be heated to form other shapes.


Imagine a world where all plastic products have to be made by hand. It goes without saying that we would have deformed and structurally weak objects that would not last a day. Low volume plastic molding manufacturing achieves precision and maintains structural strength. Here you can see the other advantages of this valuable process.



  • The use of molds reduces waste generation because the cavities are shaped so that they only contain the required amount of plastic. This leads to savings and fewer problems with waste disposal.


  • Plastic waste can be reused to form other important parts and components. This waste is qualitatively equivalent to virgin plastic. The waste is thus reduced to a minimum.


  • The labor cost of low volume plastic molding manufacturing is much lower than the cost of manually molding plastic. Productivity is high and the time required to manufacture the products is drastically reduced.


  • Injection-molded plastics have minimal or no defects. When defects occur, the defect rarely falls into the mold cavities. Common defects are burrs, uneven coating; blisters in which the raised tips create a rough and uneven surface; and empty spaces, voids on the surface. Defective products are renewed.


  • Although plastic's bad reputation is not biodegradable, it is highly recyclable and plants often use discarded and unused plastic parts.


  • The speed at which injection molded products can be manufactured enables large quantities to be produced in a short time. Small quantities of commercial pieces can also be shipped online at affordable costs. When adjustments are needed, some manufacturers invite customer projects by emailing plans or uploading them directly to the website


  • Injection molding shortens the finishing times because the process already does most of the work. Labor costs and time are further reduced.


  • When metal and glass cannot be used in certain applications, injection-molded plastic products are often the only solution. Industries such as the automotive, oil, gas and electronics (electrostatic discharges are minimized) use them regularly.


  • Injection molding machines are usually fully automatic. Therefore, operators must not be involved in risky production processes.


  • Molds are generally constructed using computer-aided manufacturing and design. This leaves much less room for error so you can make products that need to be manufactured in a certain precise way.


If you are looking for a low volume plastic molding manufacturing company in China that specializes in a wide range of designed and manufactured molded plastic products, Mold Making is the place to go.
