A: For a standard single-cavity mold, we can deliver T1 samples within 25-30 days from design approval. The complete timeline breaks down as follows: DFM analysis takes 2-3 days, mold design 4-5 days, CNC machining and EDM 12-15 days, and first trial 2-3 days. If you need modifications after T1, add another 3-5 days. For multi-cavity or complex molds, the timeline may extend to 35-45 days. We always provide a detailed project schedule upfront so you can plan your production accordingly.

A: We're flexible on MOQ depending on your project stage. For new product development, we can produce as few as 500-1,000 pieces for market testing. For established products, our sweet spot is 10,000+ pieces per order, which allows us to optimize production efficiency and offer better unit pricing. If you only need the mold (for production at your own facility), there's no MOQ for parts - you pay for tooling only, and we'll ship the mold to your designated location after successful trials.

A: Absolutely. We offer full Pantone and RAL color matching services. Just send us your color code, a physical sample, or even a product photo, and our color lab will develop a custom masterbatch. We typically achieve ΔE < 1.0 color accuracy. For critical applications, we'll send color chips for your approval before mass production. We can also do metallic, pearl, and translucent effects - just let us know your vision.

A: For parts exposed to freezer temperatures (-18°C to -25°C), we recommend high-impact ABS grades like LG Chem HI-121H or Chi Mei PA-757. These maintain excellent toughness down to -40°C without becoming brittle. If your design requires contact with food, we'll use FDA-compliant grades such as SABIC Cycolac MG47F. For parts near heating elements or requiring flame retardancy, we suggest ABS V-0 rated materials. During our free DFM review, we'll recommend the optimal grade based on your specific application requirements.

A: We implement a multi-layer quality control system. First, our molds are built with high-quality P20 or H13 steel with ±0.05mm precision, ensuring stable dimensions over 500,000+ cycles. During production, we maintain strict process parameters - barrel temperature, injection pressure, cooling time - all monitored by our MES system. We conduct SPC sampling every 2 hours using CMM measurements on critical dimensions. Before shipment, we provide a full ISIR (Initial Sample Inspection Report) with CPK values above 1.33 for key features.

A: Yes, we have extensive experience with both processes. Insert molding is commonly used for metal bushings or threaded inserts in fan shroud mounting points - this eliminates secondary assembly operations. Over-molding works great for soft-touch grips or vibration-dampening features using TPE over the ABS substrate. Our facility has dedicated machines for these processes with proper insert heating and precise positioning fixtures. Share your assembly requirements, and we'll suggest the most cost-effective approach.

A: We offer the full SPI finish range. For visible interior surfaces, most customers choose SPI-B1 to B3 (semi-gloss, 400-600 grit polish) - this hides fingerprints while maintaining a quality appearance. For high-end refrigerators, SPI-A2 high polish creates a premium glossy look. For parts that shouldn't show scratches, we recommend VDI textures (VDI 24-30) or custom leather grain patterns. EDM spark finish is also popular for a uniform matte appearance. We can apply different finishes to different surfaces of the same part if needed.

A: We prefer 3D files (STEP, IGES, Solidworks, or Pro/E formats) as they allow for accurate moldflow simulation and DFM analysis. However, if you only have 2D drawings or even just a physical sample, our engineering team can create 3D models for you - this service is included free with your mold order. For reverse engineering from samples, we use 3D scanning with ±0.02mm accuracy. Just send us what you have, and we'll make it work.

A: Minor modifications are typically included in our mold quotation - this covers small adjustments to dimensions, gate location tweaks, or minor flow improvements based on T1 results. We understand that first samples rarely hit 100% of targets, so we budget for this. Major design changes (adding features, changing wall thickness significantly, or re-positioning parting lines) would be quoted separately. We always discuss any potential additional costs transparently before proceeding. Our goal is to get your mold production-ready as efficiently as possible.

A: We ship molds worldwide and have extensive experience with international logistics. Molds are packed in custom wooden crates with anti-rust treatment, moisture barriers, and shock-absorbing materials. We typically use sea freight for cost efficiency (15-30 days to most destinations) or air freight for urgent projects. For customs, we provide all necessary documentation - commercial invoice, packing list, material certificates, and country-of-origin certificates. We can ship DDP (Delivered Duty Paid) where we handle all customs clearance, or DAP/FOB if you prefer to use your own customs broker. Just let us know your preference.
