Like anything in life, there are degrees of perfection. This is true in plastic injection molding. Some molders specialize in lower volume parts that don’t require a high level of detail or precision. This type of manufacturing may be suitable as some projects don’t require a perfect part based on the application. Take disposable cutlery for instance. Because of its “use and toss” status in this world, plastic knives and forks don’t need to maintain a high level of perfection. They can have a bit of flash around the perimeter, and no one gives it a second thought. However, parts that need to meet exact standards are a very different story. When you need precision parts, you need to use a precision molder. These craftspeople are trained to build molds within very tight tolerances. They take into consideration the part complexity, the material used as well as the final application of the part to determine the best approach for manufacturability.

2. What is a precision injection
molding company?
They manufacture parts that need
to meet exact specifications
- Specializes in close tolerance molds
- Tooling built for resin variances
- Produces high-volume parts
- Hardened steel molds for long
production runs

3. When to use a precision
molder
Your part…..
– Must meet very tight specifications
– Has complex geometries
– Require long-lasting performance
– Must meet FDA, RoHS or other guidelines
– Require consistent, long-term results

4. When you to use other
molders
Your part…
– Doesn’t need to meet exact specifications
– Imperfections like flash are acceptable
– The production run is small
– Only prototypes are required
– Has a short usage life span
– Is fairly simple in design

5. Other molding options
Additive manufacturing (3-D Molding)
- Good for low volume, prototype molding
Low volume molding using aluminum tools
- Good for shorter production runs
High volume, low precision molds
- Good for products where variations are acceptable
- Example – plastic forks
