High-Temperature Injection Molding FAQs
How do I choose a high-temperature plastic for my part?
Share the continuous operating temperature, short-term peaks, mechanical loads, and chemical exposure. Include electrical, flame-rating, or sterilization requirements where relevant. The exact resin grade and reinforcement should be evaluated against these conditions before tooling.
Can an existing injection mold be used with a high-temperature resin?
It requires an engineering review. The mold’s temperature-control system, steel, gates, venting, and shrinkage allowance must suit the selected resin. A mold designed for another material may need modification or replacement, and the molding equipment must also support the required processing conditions.
What information is needed for a quote?
Send your 3D CAD files, available 2D drawings, resin specification, order quantity, and target delivery date. Identify critical dimensions, cosmetic surfaces, service conditions, and any inspection or documentation requirements.
What affects the cost of injection molded parts?
Cost depends on part geometry, mold complexity, cavity count, resin grade, cycle time, and production quantity. Secondary operations and inspection requirements also affect the quote. Consider the tooling investment together with the recurring cost per part.
Can I review samples before production?
Yes. Trial samples are provided for review before production approval. Sample quantities, dimensional reports, functional checks, and acceptance criteria should be agreed during project planning.
What tolerances can be achieved?
Achievable tolerances depend on the resin grade, reinforcement, part size, geometry, and tooling. Mark critical dimensions on your drawing so their feasibility and inspection method can be reviewed during DFM.
Do you support low-volume production?
RJC supports prototype quantities, pilot runs, and mass production. Share your initial order quantity and expected future demand so the tooling approach can be evaluated for your project.
How long do tooling and production take?
Timing depends on mold complexity, resin availability, sample iterations, and order quantity. The project schedule is confirmed during quotation, with tooling, trial samples, and production after sample approval identified separately.
