Low volume mold building necessitates a combination of technology, equipment and qualified mold builders to create injection molds quickly with an almost limitless geometry for the plastic components.
One of the key differences between low-volume injection molding and traditional injection molding is the speed of production. Traditional injection molding is slower than low-volume injection molding. Traditional injection molding also has more complexity to the mold designs which can increase the time needed to make the parts. Because of this, there are many key advantages for choosing low-volume injection molding over traditional methods.

Some key advantages for low-volume injection molding include:

Mold Cost: In many cases, low-volume manufacturing has lower overhead costs. Also, low-volume molds are usually cut from high-quality aluminum, which is easier to make and modify than other types of metals.
Quick Production: Low-volume injection molding usually takes 1-3 days whereas mid-volume takes 3-4 weeks and high-volume injection molding takes 4-8 weeks. This quick production of parts allows for a faster fulfillment for orders in markets where time is crucial.
Inventory Management: If a company orders parts and receives more than their inventory can manage, this can cause issues for a company’s bottom line. Requiring more storage space, waste of inventory due to disposal of unsold products, and lower productivity. Low-volume injection molding can help regulate your inventory by giving you a range of products closer to your required quantities.
Disadvantages of Low-Volume Injection Molding
While there are great advantages to choosing this type of molding there are some disadvantages too.

Net Cost of Tooling: While cheaper by itself, the net cost of tooling will be higher if they later transition to medium or high volume molding. As opposed to beginning with a more durable option right away.
Shorter Product Life: The cost savings aren’t always worthwhile for the sacrifice in durability. We advise against aluminum tooling unless product life is 20000 parts or fewer, and there are many qualifiers that go with that pertaining to part design.
Design Constraints: Low-volume tooling, usually aluminum, has more design constraints because of the durability issues aluminum has. A design that would easily work in a steel mold may cause an aluminum mold to wear out prematurely.
