Mold spare parts
Case Study | Fountain Pen Refill Mold Customer—One-Stop Supply of Mold Components and Consumables
Process: Provide a quote within 24 hours; select materials based on operating conditions (e.g., S136 corrosion-resistant mirror-polished steel or NAK80 pre-hardened steel); mold core precision of ±0.01 mm; procure wear-prone components such as O-rings, springs, and pins as complete sets, subject them to unified quality inspection, and ship them together.
Results: The supply chain has shifted from “multiple points of contact” to “just contact us.” — Communication and management costs have been reduced by approximately 50%, logistics costs have been cut by about 20%, and the overall procurement cycle has been shortened by about 15%, thereby freeing up resources for production continuity and management.

Case Study | Non-Standard Prototype Parts · Small-Batch Precision Machining
Pain Points: Prototypes fail to operate as planned, parts don’t arrive on time, and there’s constant back-and-forth communication over “drawing approvals”—this is simply unacceptable.
Solution: Our engineers will communicate directly with you—not only to convey information, but also to jointly review drawings, evaluate critical fits (with precision controlled within ±0.01 millimeters), select materials such as 6061, Cr12, or 40Cr based on operating conditions, and provide recommendations for process optimization. A single technical briefing can significantly reduce the need for repeated confirmations and waiting times, while clearly establishing a delivery date.
Frequently Asked Questions (FAQ)
Find answers to the most common questions about our CNC machining services, ordering process, and quality standards.
🕒 Lead Time & Production
Q1: What is your typical lead time for custom CNC parts?
A: For standard prototypes or small-batch orders (1–50 pieces), our typical lead time is 7–15 business days. For complex projects involving heat treatment or special coatings, the lead time is usually 3–5 weeks. We never quote “unrealistic lead times” just to win an order; instead, we base our quotes on our real-time production capacity. If you have a tight deadline, please let us know—we can usually offer expedited service.
Q2: Do you accept small quantity orders or urgent "rush jobs"?
A: Yes. Unlike large factories that focus solely on mass production, we specialize in supporting small and medium-sized businesses. We accept orders starting at just one unit. For urgent repair parts and replacement parts for equipment failures that cannot wait for standard lead times, we have a dedicated “Rapid Response Hotline.”
Q3: How do I track my order status?
A: Transparency is key to our partnership. We’ll provide progress updates accompanied by real-time photos (e.g., incoming raw material inspections, completion of rough processing, final inspections). You won’t have to guess—we’ll proactively send updates instead of making you go out of your way to ask for them.
🔍 Quality Control & Materials
Q4: How do you guarantee dimensional accuracy?
A: All critical dimensions are inspected using our coordinate measuring machine (CMM). We provide a quality inspection report (QIR) with each shipment, which lists the actual measurement data alongside the drawing tolerances. If the products do not meet specifications, we will remanufacture them at our own expense.
Q5: Are your materials genuine? Do you provide certificates?
A: Of course. We source our raw materials directly from certified manufacturers such as Baosteel, ASSAB, and Thyssen. Each order is accompanied by a Material Test Report (MTR). We strictly prohibit the substitution of materials without the customer’s written approval.
Q6: What about surface finish and deburring?
A: Unlike many suppliers who only ship unprocessed blanks, our standard quotes already include complete deburring, chamfering, and standard rust-preventive oil. The parts you receive are ready for immediate assembly, saving you on workshop labor costs.
🛠️ Technical Support & Communication
Q7: My drawing has very tight tolerances. Can you actually achieve them?
A: We typically maintain a tolerance of ±0.01 millimeters for CNC machining and ±0.005 millimeters for grinding. However, we adhere to DFM (Design for Manufacturability) principles. If we find that achieving a particular tolerance is too costly, we will note this and recommend a more cost-effective alternative. beforeproduction starts.
Q8: Will I talk to a salesperson or an engineer?
A: We will assign you an English-speaking project engineer. They are well-versed in Geometric Dimensioning and Tolerancing (GD&T), material properties, and manufacturing processes. Compared to sales representatives without a technical background, this effectively reduces misunderstandings and speeds up problem resolution.
💰 Pricing & Hidden Costs
Q9: Is your quote all-inclusive? What about shipping and packaging?
A: Our quotes clearly itemize all costs. By default, we include export packaging that meets maritime shipping standards (fumigated wooden crates). We also offer both EXW/FOB and DDP (Delivered Duty Paid) options, allowing you to know the total cost upon arrival in advance and avoid unexpected customs fees.
Q10: Do you charge extra for standard threading/tapping?
A: No. Unless otherwise specified in the quote, standard threading, tapping, and countersinking are all included in our machining fees. Just like you, we hate the surprises that come with “hidden fees.”
🔩 Standard Parts & Consumables
Q11: How do I know your bearings/seals/fasteners are genuine?
A: We supply only OEM-grade parts from authorized distributors (such as SKF, NSK, SMC, and Festo). Upon request, we will provide part numbers and original packing lists to ensure full traceability and prevent counterfeit products.
Q12: Can you consolidate shipments to save freight?
A: Yes. We offer combined shipping. If you need multiple items within a month, we can hold your inventory for you and combine shipments to optimize your shipping costs, especially for air freight.
📑 IP Protection & Compliance
Q13: How do you protect my intellectual property (IP)?
A: We take intellectual property very seriously. Before accepting any drawings, we will sign a non-disclosure agreement (NDA). Your files will be stored on an encrypted server with restricted access. We will never use your designs for other clients or display them publicly without your permission.
Q14: Can you handle export documentation for audits?
A: Yes. We provide complete commercial invoices, packing lists, certificates of origin, and material reports, all of which meet the requirements for your company’s ISO audits or customer audits.
🔄 Returns & Defects
Q15: What if the parts don't fit or there is a defect?
A: We take responsibility for our work. If the error is on our part, we will immediately remake the item and reship it at no charge.
Q16: What is your warranty policy?
A: Answer: We offer a 12-month warranty covering manufacturing defects. This warranty does not cover normal wear and tear or misuse, but it guarantees the quality of the materials we use and the integrity of our craftsmanship.
