Injection Molding Service -The Ultimate FAQ Guide

In our childhood, we played with barbie dolls, Joe action figures, or flashy toy cars. Even today our cell phones have plastic covers, and our cars have many plastic parts. For your pretty interest, all these are made by using the injection molding process. 

It contains a forming process that uses molds and produces parts in bulk quantity

Injection molding service is an easy way to produce products and parts and can digest many types of plastics and materials. 

Materials used in injection molding can be glasses, confections, and elastomers, and are usually used with thermosetting and thermoplastic polymers. Now the question arises why is it called injection molding? 

Owing to the resemblance with injection syringe, it is known as injection molding, where the material is heated and melted. After that, the melted material goes to the mold where it is cool for diverse shape designs. 

With the help of injection molding machines, complex and diverse shape designs are manufactured and achieved in large volumes thus used in a wide range of industries. Usually, the injection molding process has six parts… 

  1. Clamping
  2. Injection
  3. Dwelling
  4. Cooling
  5. Mold opening
  6. Removal of products



As we know, injection molding service is the most common method to produce identical parts in high volumes because it is reliable, efficient, and simple. However, unlike every process, to help, we simply laid out the advantages as well as disadvantages to consider. 

Advantages Of Injection Molding service

Fast Production

To consider injection molding is a very efficient and effective form of molding, so it is much faster than other methods. Its high production output makes it cost-effective and efficient. 


In a limited time with short cycles, you can produce a greater mass of mold thus increasing the profit margin and revenue. 

Complex Part Design

The most interesting advantage is it can handle even complex parts easily. It is able to create millions of identical parts. 


With the right design, you can make quality parts consistently and without design you can face costly losses. 

Enhanced Strength 

Strength is another point you should consider when designing a part from injection molding. First of all, the designer needs to know the part should be flexible or rigid, thus integrating ribs are adjusted according to it. 


Materials play the most important role in the strength of the part along with the environment. 

Reduced Waste

If you\’re looking for high-quality injection molding meanwhile you should consider green manufacturing initiatives, as they are committed to optimal safety and quality sustainability. 


Because excess plastic is created during the molding process, you should look for a system that can recycle excess plastic. 


We provide eco-friendly injection molding machinery to minimize waste, packaging, and transportation. 

Low Labor Costs

As compared to other molding processes, labor cost is very low in the injection molding process. The molding equipment runs with an automatic tool (even a sole operator can carry and manage the task) to keep production ongoing and needs minimal provision. Automation helps to diminish manufacturing costs, as the overheads reduce. 


Disadvantage Of injection molding

It is known that injection molding has plenty of advantages while it has drawbacks too. 

Cost Of time

Owing to the tool complexity, and essential steps to remove the previous materials from the machine before starting the new procedure, all this process can be lengthy. That\’s the reason, small parts are considered too expensive in injection molding. 

Part design restrictions

It is important to consider that there are some design restrictions for plastic injection molding. However, to work alongside our design expertise, you can be able to overcome initial issues. 

High machinery cost

The beginning cost of the injection molding can be high, thus the after cost is very low.

It is another disadvantage of injection molding that there is high initial machinery and tooling cost. Up-front cost is high owing to the design, testing, and required tooling. But in the initial phase and after crossing the first step it becomes reasonable. 

Considerations Before Going 

Design Factors

Plastic parts created with injection molding can be custom-designed parts. Mold design can cost you hundreds of millions of dollars if you don\’t consider the design at first or before cutting the metal. 


As we know, plastic flows along the least resistance path, and a thick/thin flow will create uneven cooling and gaps. We have a solution. What you need to do is build a CAD design, stimulate the injection process, adjust it, and try again and again for final outcomes. 

Measure, Measure, Measure

Oftentimes, sample models are created for the test part. It helps to check the temperature, flow rate, and adjustment. Mold is the biggest investment in plastic parts, so getting the right piece is crucial for success. Getting the mold wrong will cause you high costs and increase the rework process. 

Production Considerations

The use of the hot runner\’s system is production saving for our parts. If you minimize the assembly requirements then it will also prove cost-saving for you. Also, if you minimize the cycle time, it will aid in the production process. Quantity of parts you want to produce, then determine the cost, if it fits according to your budget then go for it.
