Precision making

RJC precisely mold making using 5-axis and EDM processes.Many dies are machined so precisely that they have a tolerance of less than one-thousandth of an inch.

Our 5-axis machine cuts across X, Y and Z axes along with rotating on the A and B axes. 5-axis CNC machining enables us to do the most complicated mold designs for our clients.

Our engineers will choose the correct material for the mold based on its intended application.

Plastic molds are commonly used with softer materials and for short production runs. Metal molds made out of steel, aluminum and other alloys have the durability to last for long product runs.To learn tips for designing for the injection molding process,

If you have questions regarding current or future projects, please contact RJC any time.

choose the correct material

At RJC, we make great tools for low-volume manufacturing. When making your mold tool we use pre-hardened tool steels such as P20 and NAK-80 and fully-hardened S136 tool steel.

The material used will depend on your specifications, the type of raw materials that RJC uses, and the number of parts you want to produce. Such as PP , PP+GF(20%/30%),ABS , PC/ABS , PC,PA66 ,POM,PA66+GF( 20%/30%/40%),PPA, PPS,TPE , TPU , TPV etc……

Expert manufacturability analysis.

Commonly known as DFM and moldflow analysis, our team of engineers perform expert manufacturability analysis on your injection molded parts at no charge. As a result, we have netted savings to our customers of up to 50% reduction in manufacturing costs!.

Design for Manufacturability (DFM), or more specifically analysis of a part design for its suitability to being injection molded, is performed to achieve the following:

  • Minimize Tooling Costs
  • Reduce Design Changes
  • Expedite the Manufacturing Process
  • Ensure Part Quality

RJC performs a manufacturability analysis on each injection molding project.

Upon receiving a quote request and an appropriate 3D design file, we will perform an initial analysis to ensure that the requested component is an appropriate candidate for injection molding.

Our objective is to produce the component closest to the original design intent. However, modifications are needed to accommodate the fundamental requirements of good injection molding practice in some instances.

In these cases, we discuss with clients suggested improvements to the design or measures we may need to take in the production process before initiating the mold production process to save our customers by minimizing tooling costs and design changes upfront and reducing overall project time.
