A: The optimal cavity number depends on your production volume and injection machine specifications: 2-4 cavities: Small batch production (10,000-50,000 handles/day) or trial runs - ideal for new product development 8-16 cavities: Medium to large production volume (50,000-200,000 handles/day) - most common configuration for beverage manufacturers 24-32 cavities: Mass production (200,000+ handles/day) for large beverage companies with high-speed injection machines Our engineers will recommend the best cavity number based on your monthly production target, injection machine tonnage (recommended: 250-500 tons for 8-16 cavity molds), and budget considerations. We also consider future production expansion in our recommendations.

A: Standard lead time is 25-45 working days, depending on complexity and cavity count: Design confirmation: 3-5 days (includes mold flow analysis and technical review) Material preparation: 2-3 days (we maintain inventory of common mold steels for faster delivery) CNC machining & EDM: 15-25 days (longer for higher cavity counts or complex designs) Polishing & assembly: 3-5 days (mirror polishing adds 1-2 days for premium finish) Testing & adjustment: 2-4 days (includes 1000-shot trial production and quality verification) We offer expedited service (15-20 days) for urgent orders with additional cost (typically 20-30% premium). For standard mold designs (non-custom), we can deliver in 15-20 days with our pre-engineered mold bases.

A: We use premium mold steels based on your production requirements and budget: S136 (Stavax): Best for high polish finish and corrosion resistance (most recommended for plastic handle molds) - ideal for food/beverage packaging with strict hygiene requirements H13 (SKD61): High toughness and wear resistance for high production volume (1 million+ shots) - excellent for continuous 24/7 production 718/P20: Cost-effective option for medium production volume (500,000 shots) - good for lower volume or seasonal production All steels are imported from reputable suppliers (ASSAB, Bohler, Hitachi) and pass strict quality inspection before use. We can also provide material certification (mill test reports) for all steel used in your molds. For special applications, we offer surface treatments like nitriding or TiN coating to extend mold life by 30-50%.

A: Yes, we provide comprehensive after-sales service that sets us apart from competitors: 12-month warranty for mold quality issues (covers all manufacturing defects) Free technical support for mold installation and operation (on-site support available for major projects) Spare parts supply at factory price (we maintain inventory of common parts for fast delivery) Mold maintenance and repair service (we can refurbish molds to extend their life by 50-100%) Remote technical support 24/7 (phone, video call, email, WhatsApp) Mold optimization service (we can modify existing molds to improve performance or adapt to new bottle designs) We also provide mold operation and maintenance training for your staff (on-site or online) to ensure optimal performance and longevity. Our average response time for technical support is less than 4 hours for urgent issues.

A: Absolutely. We have a professional R&D team with rich experience in custom handle mold design (15+ years specializing in PET packaging molds). We can make molds based on: Your physical handle sample (we use 3D scanning for precise replication) 2D/3D drawings (PDF, DWG, STEP, IGES, STL, etc.) - we accept all common file formats Your bottle specifications and design requirements (we can create new handle designs from scratch) Concept sketches or verbal descriptions (our industrial designers can create 3D models for your approval) We will provide 3D design confirmation, mold flow analysis report, and prototype samples before mold manufacturing to ensure it meets your expectations. For complex designs, we can produce 3D printed prototypes of the handle for fit testing before mold production.
