Frequently Asked Questions (FAQ)
Q1: What materials can be used with this mold?
A: The mold is optimized for PMMA (acrylic), but it also works well with PETG, SAN, and other transparent or semi-transparent resins. Please advise your specific material for best results.
Q2: What is the typical lead time for this mold?
A: For a standard 1x4 cavity mold, lead time is approximately 25–35 days after design approval. Rush orders can be accommodated upon request.
Q3: Can you make molds for larger cavity counts, like 1x8 or 2x4?
A: Absolutely. While our standard for cosmetic jars is 1x4, we can design molds with 1x8, 2x4, 2x8, or any configuration to match your production volume. Just provide the required specifications.
Q4: How does the mirror polish affect part ejection?
A: The mirror finish is combined with a slight draft angle (typically 1–3°) to ensure smooth ejection without sticking. Our experienced engineers optimize the polish and draft for your specific part geometry.
Q5: Do you provide samples before mass production?
A: Yes, we offer T1 samples for your approval. After sample approval, we proceed with full production. Sample shipping is available via FedEx, DHL, or sea freight.
Q6: What is the warranty period for this mold?
A: We provide a 12-month warranty against defects in materials and workmanship under normal operating conditions. Extended warranty options are available upon request.
Q7: How do you ensure the mold produces consistent jars?
A: Our molds undergo comprehensive testing including dimensional inspection, surface roughness measurement, and trial runs. We also provide a mold qualification report with every delivery.
Q8: Can you add logos or text to the jar via the mold?
A: Yes, we can engrave logos, brand names, or other markings on the cavity using CNC or EDM. This is a cost-effective way to customize your jars without secondary printing.
