Frequently Asked Questions
1. Can a rubber compression molding supplier also manufacture SMC or BMC composite parts?
Not necessarily. Rubber compression molding commonly uses elastomers such as EPDM, NBR, silicone, and natural rubber, while SMC and BMC are fiber-reinforced thermoset composite materials that require suitable compounds, molds, heating systems, and process controls. Before requesting a quote, identify the exact material family and ask for examples of comparable parts produced using that material. For rubber seals or vibration isolators, evaluate rubber-specific tooling and testing experience; for fiberglass-reinforced electrical housings or industrial composite components, verify SMC/BMC molding capability and the relevant electrical, mechanical, or thermal test facilities.
2. How can I check whether a compression molding supplier in Mexico can meet my required delivery date?
Ask the manufacturer to provide separate lead times for mold design, tooling fabrication, first-trial samples, sample approval, and mass production. For reference, some Mexican rubber molding suppliers publish standard production lead times of around 6–8 weeks, but this should not be treated as a universal schedule or as including new tooling. Request a dated project plan and confirm how many trial rounds are included, how quickly the supplier can correct rejected samples, and whether raw materials are already available before committing to a delivery date.
3. Why can the initial compression mold quote be low but the final tooling cost much higher?
The original quote may exclude mold modifications, trial runs, sample inspection, spare inserts, maintenance, or transportation. Request an itemized quotation covering mold design, machining, initial trials, the number of included correction rounds, and additional revision charges. For example, if a mold costs $8,000 and produces 10,000 accepted parts, its initial tooling allocation is $0.80 per part before maintenance and other costs. Confirm in writing who owns the mold, where it will be stored, and whether it can be transferred to another manufacturer if production needs change.
4. What should I do if compression-molded parts have excessive flash or inconsistent dimensions?
Ask the manufacturer to investigate the mold parting surface, mold wear, material charge weight, material placement, temperature, pressure, and curing conditions rather than simply removing more flash. Provide the drawing with critical dimensions and define acceptable flash height, trimming limits, and inspection methods before production. Request a first-article inspection report and measurements from at least 5–10 samples as an initial screening set; this is not a substitute for a statistically valid capability study. If the defect repeats, require a documented root-cause analysis and corrective-action plan before approving the next production batch.
