FAQs
Injection molding hourly rates typically range from $20 to $150, depending on part complexity and machine type.
3D printing, vacuum casting, and CNC machining can be cheaper alternatives for low-volume or prototype parts.
Injection molding costs per part range from a few cents to several dollars, depending on factors like material, complexity, and production volume.
Injection molding has many advantages but the one that stand out the most is the support for mass production of parts. This in turn reduces the cost of production due to the lower cost per unit part as production increases.
Additionally, it is compatible with parts with complex geometries, providing consistency during production.
Common defects you can encounter during injection molding include the following:
- Warping
- Sink marks
- Flashes
- Short shots.
These injection molding defects can occur due to improper mold design, wrong material choice, wrong tooling, or the use of the wrong injection molding technique
Injection molding typically takes 2-8 weeks. But KG Model can basically guarantee completion within a week.
Other factors that can alter the production time include the parts design complexity, size, injection service provider capabilities, and the production volume.
KG Precise offers a injection molding services at a competitive price.
However, you need to consider factors like mold complexity, material selection, production capability, and production volume during budgeting.
The production volume is a very important factor to consider because the higher the number of parts produced the lower the cost per unit part.
The injection mold longevity depends on the material used in making it.
There are two common materials: steel and aluminum. Steel has a higher longevity and a single steel mold can produce thousands to millions of parts hence its use in high volume production. On the other hand, aluminum molds are less durable and suitable for hundreds to thousand runs.
KG Precise has no minimum order requirement. We value every designer and engineer who invests in their dreams and ideas.
Yes, it is possible to accommodate some design changes after mold creation. However, this will come at an additional cost.
Depending on the changes required, it might need us to make a new mold.
Because it can lead to wastage of resources, ensure you communicate with us efficiently to reduce the need for changes and the associated cost.
