Frequently Asked Questions
1. How can I prevent dimensional variations between the first sample and mass-produced parts?
Identify critical dimensions and tolerances on the drawing before approving the sample, and ask the manufacturer to submit a dimensional inspection report using the same measurement datums and methods that will be used for production acceptance. For important dimensions, agree on the inspection frequency and what happens if a result falls outside tolerance. SMC and BMC parts can be affected by material variation, mold temperature, pressure, charge placement, and curing conditions, so a single approved sample does not prove that a process is stable. For recurring orders, request inspection data from multiple production cycles rather than relying only on the first article.
2. How can I estimate the actual cost of a custom compression mold in Brazil?
Do not compare mold prices alone. Request a cost breakdown covering mold design, machining, materials, trial runs, corrections, spare parts, and maintenance. Also compare the expected part price at your actual order volume, because a mold investment spread across 1,000 parts will have a different per-part impact than the same investment spread across 50,000 parts. Ask each supplier to state the assumptions behind the quotation, including mold life, production volume, and which modifications are chargeable. There is no reliable single price for all Brazilian projects without knowing the part geometry, dimensions, material, and production quantity.
3. How long should I allow for compression mold development and sample approval?
Ask the manufacturer to provide separate lead times for design approval, mold fabrication, first trial, sample inspection, corrections, and final approval instead of one overall delivery date. The actual schedule depends on part complexity, mold size, material, tooling availability, and the number of correction cycles. Request a written project schedule with milestone dates and identify which steps depend on your approval. For production planning, do not treat the first trial date as the mass-production start date; allow additional time for dimensional verification and any required mold adjustments.
4. Why do compression-molded SMC or BMC parts develop flash, and who should correct it?
Excessive flash can result from an unsuitable charge weight, worn or poorly fitting mold parting surfaces, incorrect molding pressure, or other process and tooling conditions. Record the defect location, affected quantity, material batch, and molding conditions, then ask the manufacturer to inspect the parting line and review the process settings before deciding on a correction. Agree in writing on acceptable flash limits, trimming requirements, inspection methods, and responsibility for rework. Do not automatically assume that every flash defect is caused by the mold; the cause must be established from the actual tooling and production conditions.
