Manufacturing is the process of transforming raw materials into final finished products. It gives greater output in less input. The manufacturing process always begins with the part’s design or a designed mold. There are different kinds of manufacturing process, and it takes place according to the specification of the desired product. 

What is Injection Molding?

Injection molding is the ideal process of the manufacturing process to produce small to medium, high-quality parts or components. It’s the process of feeding the material into the machine and melting the material at a heating temperature. The molten liquid injects into the designed mold to produce the parts in large volumes.   

What is Plastic Injection Molding?

Plastic molding terms as plastic injection molding. The plastic injection molding process starts with injecting molten plastic liquid into a metallic mold to produce plastic parts to come out strong.

Resources of Injection Molding:

  • Materials
  • Machines
  • Molds
  • Man Power/ Manufacturer/ Mold Maker

How to Select the Injection Molding Process:

Here, the types of injection molding as types of machine prefers: 

  • Liquid silicone rubber injection molding
  • Metal injection moldig
  • Gas-assisted injection molding
  • Thin-wall injection molding

Some are a few names of plastic injection molding types:

  • Die casting
  • Stack molding
  • Rotary molding
  • Blow moldng
  • Plastic extrusion
  • Compression molding

Top 10 Popular Materials for Injection Molding:

When it comes to selecting a material, it’s important to consider the products and availability of injection molding machines:

  • Acrylic
  • Polycarbonate (PC)
  • Nylon (PA)
  • Polystyrene (PS)
  • Polypropylene (PP)
  • Polyoxymethylene (POM)
  • Acrylonitrile Butadiene Styrene (ABS)
  • Polyethylene (PE)
  • Thermoplastic Rubber (TPR)
  • Thermoplastic Polyurethane (TPU)

How to Select the Injection Molding Machine:

  1. Types of Parts or Products: 

When it comes to buying an injection molding machine, it’s crucial to know what type of parts or components are going to mold. The machine should best fit the parts that it intends to mold into the final finished product. The material injects into the right machine leads to smooth cycle times, uniform wall thickness, gates location, mold’s performance, and quality production. It has now become easier to maintain heavy machineries with the availability of parts like full gasket set online.

  • Availability of Machine’s Type: 

Three types of the injection molding machine are available:

  • Full Electric Machine: It’s an energy-efficient machine that is suitable to make medical instruments and devices. It maintains the consistency and quality of the product.
  • Full Hydraulic Machine: Hydraulic machines with servo pumps should consider before buying. It’s also an energy-efficient and fast injection molding machine to produce thin-wall parts. 
  • Hybrid (Electric and Hydraulic) Machine: It’s a 2 in 1 machine (combination of electric and hydraulic). This is a high energy-efficient machine used to perform both functions of electric and hydraulic machines.

  • Process of Injection Molding:
  • The raw material melts at high temperatures until it turns into liquid form.
  • The molten liquid injects into a mold by hydraulic pressure to fill a mold.
  • The molten liquid starts to cool and harden inside a mold at the cooling temperature.
  • A mold ejects from the machine, once it gets cooled and solidified.
  • Remove the final finished parts and components from a mold.
  • The next cycle continues to run again for the mass-production of products in large volume.
