Injection Molding: The KEY to cost-effective manufacturing and quick turnaround times
When developing a product, it is essential to learn about the top manufacturing processes, one being injection molding. The injection molding process has grown to be one of the most efficient and cost-effective manufacturing processes because of its ability to quickly produce a large volume of identical parts. Injection molding allows for the flexibility of various shapes and sizes, resulting in a significant proportion of plastic products created in a short amount of time.
How the injection molding process works
The injection molding process begins by feeding plastic material granules into a heated barrel. The plastic granules are melted down and mixed with a helical shaped screw. The screw then injects the melted plastic into a custom mold cavity created for each product. The plastic is left to cool and harden to the mold’s configuration. Once solidified, the piece is placed on a moveable platen and removed from the machine. The process is now complete and begins to repeat to produce more parts.

Advantages of injection molding
- Speed: Each cycle is completed in about 15-30 seconds.
- Low labor costs: This process uses an automatic tool that can produce your parts with little to no labor on top of the production.
- Low production cost: Using and creating a mold that minimizes materials and produces multiple parts results in a lower price per piece.
- Low waste: There is little waste created because the mold is made custom to each part, and most products are recyclable.
- Design flexibility: These molds are the most versatile and flexible because they can create almost any shape in one piece.
- Number of cycles per mold: Each custom mold can complete about 100,000 to 1 million cycles depending on the quality, maintenance, and conditions your mold is under.
Are there disadvantages?
- High upfront cost: The high initial cost to create an injection mold can be a barrier to entry. On average, a mold can cost $12,000, but for smaller pieces, molds can range between $1,000 and $5,000, and for more extensive, it can cost up to $80,000. However, once this cost is covered, there are little costs to continue making the product.
- Part redesign restrictions: If you need to make a few changes to your parts, you will need to create a whole new injection tooling mold. To combat this problem, work with our team using our 3D printers to perfect your prototype, and ensure this does not happen.
Where to go for injection molding?
When choosing a company for manufacturing services such as injection molding, you should find a highly experienced company with a strong history in developing products that require similar expertise as the product you are trying to create. When you narrow down to your final choices, make sure you ask for case study samples of past projects or physical samples so that you can assess the quality of production.
