Frequently Asked Questions (FAQ)
-
Q: What materials can this mold process besides acrylic?
A: The mold is optimized for PMMA (acrylic) but can also run rigid PVC, PS, SAN, PETG, and other amorphous or semi-crystalline polymers. The hot runner temperature and gate design can be adjusted accordingly. -
Q: Can the mold be customized for different jar sizes?
A: Absolutely. We offer full customization on jar diameter, height, wall thickness, neck finish, and thread details. Just provide your 2D/3D prints or sample, and we will design the mold to your exact requirements. -
Q: What is the expected mold life?
A: With S136 steel and proper maintenance, our molds typically achieve over 5 million shots for acrylic materials. For aggressive materials (e.g., glass-filled), we recommend hardened steel upgrades. Regular cleaning and lubrication extend life further. -
Q: What is the delivery time and shipping ports?
A: Standard delivery is 30–45 working days after design approval. We ship from Jiangsu, Shanghai, or Shenzhen ports via sea, air, or express. Door-to-door service is available upon request. -
Q: Do you provide trial shots and samples?
A: Yes, we conduct mold trials in our own injection molding facility. You will receive 20–100 sample jars for free (shipping cost borne by client). After your approval, we start mass production of the mold. -
Q: What is the warranty policy?
A: We offer a 12-month warranty on manufacturing defects from the date of shipment. Spare parts (e.g., inserts, slides, heater bands) are covered. We also provide lifetime technical support and remote troubleshooting. -
Q: Can I get a 2D/3D drawing before placing an order?
A: Yes, we will create a preliminary mold design drawing (without core details) for your review after discussing basic specifications. Full detailed drawings are provided upon order confirmation. -
Q: What injection molding machine size is required?
A: For a 1x4 cavity thick-wall jar mold, a machine with clamp force of 80–150 tons and a minimum platen size of 500×500 mm is recommended. We can help you check compatibility.
