Each mold is engineered to client specifications with rigorous dimensional accuracy.
What mold steel grades do you typically use?
Steel selection depends on production volume, part material, and surface finish requirements. Common choices include P20 (pre-hardened, general-purpose), H13 (high-heat, long runs), S136 (stainless, corrosive resins), NAK80 (high polish, optical parts), and 2738 (large molds). We recommend the most cost-effective grade for your specific application.
What is the typical mold lead time?
리드 타임은 금형 복잡성에 따라 달라집니다. 단순한 단일 캐비티 금형은 일반적으로 3-4주가 필요한 반면, 복잡한 다중 캐비티 또는 핫 러너 금형은 6-10주가 걸릴 수 있습니다. 당사는 DFM 검토 후 상세한 프로젝트 일정을 제공하고, 스틸 구매, 가공, T1 시험 및 최종 승인 등 모든 마일스톤에서 업데이트를 제공합니다.
Do you perform mold flow analysis before building the mold?
예. 저희는 복잡한 부품에 대해 DFM(제조성 설계) 공정의 일부로 Moldflow 시뮬레이션을 수행합니다. 이 분석은 게이트 위치, 러너 밸런스, 냉각 채널 배치를 최적화하고 휨, 싱크 마크, 미성형과 같은 잠재적 결함을 예측하는 데 도움이 되며, 이 모든 것이 강재를 절삭하기 전에 이루어집니다.
What is the expected mold lifespan / shot count?
Mold lifespan is categorized by SPI standards. Class 105 prototype molds are designed for under 500 shots, Class 104 for up to 100,000 shots, Class 103 for up to 500,000, Class 102 for up to 1,000,000, and Class 101 for over 1,000,000 shots. We match steel grade, heat treatment, and build quality to your required shot count.
Can we own the mold and ship it to our facility?
Yes. Upon full payment, all molds are 100% client-owned. We can ship the mold directly to your facility or a designated third-party location worldwide. We will provide complete mold documentation including drawings, maintenance guides, spare parts list, and a material certificate before shipping.
What plastics and materials can you process?
ZetarMold has experience with over 400 different materials including commodity plastics (PP, PE, PS, ABS), engineering plastics (PC, POM, PA, PBT, PET), high-performance materials (PEEK, PEI, LCP, PSU), and specialty compounds (glass-filled, flame-retardant, UV-stabilized grades). We can advise on the best material for your application.
What injection machine tonnages are available?
Our facility houses 45 injection molding machines ranging from small-tonnage presses for precision micro parts up to our largest 1,850-ton press, which can produce single-shot parts weighing up to 10 kg. This wide range ensures we can handle both tiny intricate components and large structural parts.
Do you have cleanroom molding capabilities?
Yes. We operate 6 injection molding machines within an ISO Class 7 (M7-grade) cleanroom environment. This cleanroom is essential for producing medical devices, optical components, and other parts that require contamination-free manufacturing conditions. All cleanroom operations comply with ISO 13485 requirements.
What is your minimum order quantity (MOQ)?
We do not enforce a strict MOQ. However, injection molding is most cost-effective for volumes of 1,000 units and above due to the upfront tooling investment. For smaller volumes, we may recommend alternative processes such as prototyping or 3D printing. We are happy to discuss the most economical solution for your specific volume needs.
How do you ensure part quality and consistency?
Our quality control process includes incoming material inspection, in-process monitoring, first article inspection (FAI), CMM dimensional measurement, visual inspection, and final outgoing QC. We provide full inspection reports and can supply PPAP documentation upon request. Statistical process control (SPC) is implemented on critical dimensions.
What 3D printing technologies do you offer?
We offer multiple additive manufacturing technologies including FDM (Fused Deposition Modeling), SLA (Stereolithography), SLS (Selective Laser Sintering), and MJF (Multi Jet Fusion). Each technology has distinct advantages in terms of surface finish, material properties, build volume, and cost, and we will recommend the best fit for your application.
What file formats do you accept for 3D printing?
We accept STL, OBJ, STEP, IGES, and SolidWorks (.SLDPRT) file formats. STL is the standard for 3D printing. If you only have a 2D drawing or sketch, our engineering team can assist with 3D modeling at an additional fee. Please ensure your 3D file is watertight (no open surfaces) for best results.
How does 3D printing compare to injection molding?
3D printing offers no tooling cost, fast turnaround (often 1-5 days), and geometric freedom for complex shapes, making it ideal for prototyping and low volumes. Injection molding requires upfront mold investment but delivers superior surface finish, tighter tolerances, wider material options, and much lower per-unit cost at scale. They are complementary, not competing, technologies.
What is the typical lead time for 3D printed parts?
Standard lead times range from 1-5 business days depending on part complexity, size, quantity, and chosen technology. Rush services may be available upon request. Post-processing operations such as sanding, painting, or coating may add additional time. We provide a precise timeline at the quotation stage.
Can 3D printed parts be used for functional testing?
Yes, depending on the technology and material chosen. SLS Nylon and MJF parts exhibit good mechanical properties suitable for fit, form, and function testing. SLA parts are better suited for visual and fitment checks. For rigorous functional testing that mimics production-grade mechanical properties, we recommend CNC machined prototypes or short-run injection molded parts.
What prototyping methods does ZetarMold provide?
자주 묻는 질문
How fast can you deliver a prototype?
3D printed prototypes can often be ready in 1-3 business days. CNC machined prototypes typically take 3-7 days. Urethane cast parts take 7-14 days including master pattern creation. Rapid injection molded prototypes (soft tooling) typically take 2-4 weeks. We offer expedited services for urgent development cycles.
What is vacuum casting and when should I use it?
Vacuum casting uses a silicone mold (made from a master pattern) to produce polyurethane parts that closely mimic injection-molded ABS or PP. It is ideal when you need 5-50 functional prototype units with production-like appearance and material properties, at a fraction of the cost and time of a steel mold. Perfect for pre-production validation and investor presentations.
Can you help with design optimization before prototyping?
예. 저희 엔지니어링 팀은 언더컷, 얇은 벽, 구배 각도, 조립 충돌과 같은 잠재적 제조성 문제를 조기에 식별하기 위해 철저한 DFM 검토를 수행합니다. 저희는 실행 가능한 피드백을 제공하며, 부품 품질을 개선하고 비용을 절감하며 양산 준비 툴링까지의 경로를 단축하기 위한 설계 수정을 지원할 수 있습니다.
Do I need a complete design to start prototyping?
Not necessarily. If you have sketches, reference samples, or basic concept drawings, our product design team can help develop full 3D CAD models ready for prototyping. We offer product design and reverse engineering services to bridge the gap between idea and manufacturable part, all under one roof.
What types of silicone rubber parts can you manufacture?
We produce a wide range of liquid silicone rubber (LSR) and high-consistency rubber (HCR) parts including seals, gaskets, O-rings, keypads, medical-grade components, infant products, wearable parts, and overmolded silicone-on-plastic assemblies. Our cleanroom facility is particularly suited for medical and food-contact silicone products.
What is the difference between LSR and HCR silicone?
LSR (Liquid Silicone Rubber) is a two-component platinum-cured system processed by injection molding. It produces consistent, precise parts with excellent surface finish and is well-suited for high-volume production. HCR (High Consistency Rubber) is a solid, peroxide-cured material typically processed via compression or transfer molding, better suited for larger parts and lower volumes.
Is your silicone molding suitable for medical and food-contact applications?
Yes. We use USP Class VI, FDA-compliant, and REACH/RoHS-compliant silicone materials for medical and food-contact applications. Our ISO 13485 certification and Class 7 cleanroom environment ensure that products meet the highest hygiene and safety standards. We can provide full material traceability and biocompatibility documentation.
Can you overmold silicone onto plastic substrates?
Yes. We specialize in silicone-over-plastic overmolding, where a rigid thermoplastic substrate (e.g., PC, PA, PP) is insert-molded into the silicone mold. The silicone bonds chemically or mechanically to the substrate, creating a seamless multi-material assembly. This is common in medical devices, handles, wearables, and consumer electronics.
What shore hardness options are available for silicone parts?
We can process silicone with Shore A hardness ranging from 10A (very soft, gel-like) to 80A (firm, rubber-like), depending on the application. Common selections include 20-30A for skin-contact wearables, 40-60A for general seals and gaskets, and 70A+ for structural silicone components. We help you select the right durometer for your functional requirements.
What post-processing services does ZetarMold offer?
We provide a full suite of post-processing services including spray painting, pad printing, silk screen printing, hot stamping, laser engraving, ultrasonic welding, heat staking, insert pressing, chrome plating, anodizing, powder coating, and custom surface texturing. All finishing operations are performed in-house to maintain quality and timeline control.
Can you apply custom colors and finishes to molded parts?
Yes. We match colors using Pantone, RAL, or client-supplied color codes. Surface finishes can range from high-gloss (SPI A1/A2) to matte and textured (VDI/Mold-Tech standards). Our dedicated painting and printing workshop handles multi-color spray painting, special effect coatings (soft-touch, metallic), and decorative printing with precise color consistency.
What printing methods are available for part decoration?
We offer pad printing (ideal for curved surfaces and small logos), silk-screen printing (flat surfaces, high-volume runs), hot stamping (metallic foil transfer), and laser engraving (permanent, precise markings without ink). We help you choose the most appropriate method based on part geometry, durability requirements, and production volume.
Can you perform secondary machining on molded parts?
예. 저희는 임계 보어 직경, 나사 절삭, 정밀 결합면, 트리밍과 같이 사출 성형만으로는 달성할 수 없는 더 엄격한 공차가 필요한 형상에 대해 성형 부품에 2차 CNC 가공 작업을 수행합니다. 이 하이브리드 접근 방식은 성형의 속도와 가공의 정밀도를 결합합니다.
