Frequently Asked Questions - XH Mould Tooling & Engineering

Question 1

What machining tolerances and tooling precision can XH Mould consistently achieve?

Accepted Answer

Equipped with high-precision Makino CNC machining centers, Sodick mirror EDM machines, and Sodick slow-feeding wire electrical discharge cutting equipment, our cavity and core insert tolerances are held within ±0.002mm (±0.00008 in), with electrode precision reaching ±0.001mm. Every finished tooling set is verified with a comprehensive dimensional report from our temperature-controlled ZEISS 3D Coordinate Measuring Machine (CMM).

Question 2

What mould tool steels do you use, and what is your mould lifespan guarantee?

Accepted Answer

We select certified virgin tooling steels strictly based on plastic resin properties and production volume targets. Primary steels include Uddeholm/Assab S136, S136H, 718H, German Kind & Co / Deutsche Edelstahlwerke 1.2343, 1.2344, and Japanese Daido NAK80 or DC53. Our precision moulds are engineered for 300,000 to over 1,000,000 injection shots, built upon certified LKM, HASCO, or DME standards.

Question 3

Which industries and applications do you primarily support?

Accepted Answer

Founded in 1985, XH Mould specializes in large and medium precision injection tooling for automotive components and premium household appliances. Automotive applications include headlamp lenses, 2K/multi-shot housings, instrument cluster bezels, door panels, and heat-resistant under-the-hood structural brackets. Appliance applications encompass air conditioner structural grilles, washing machine front bezels, refrigerator aesthetics, and precision electro-mechanical frames.

Question 4

How do I request a tooling quotation, and how fast is the DFM turnaround?

Accepted Answer

You can submit part geometry via our online RFQ portal or email technical data to xhmould@126.com. Our engineering team commits to a 24-hour turnaround SLA, providing a comprehensive Design for Manufacturability (DFM) assessment covering draft angles, parting lines, gate positioning, cooling channel feasibility, Moldflow filling simulations, and transparent milestone pricing.

Question 5

Which CAD / CAM / CAE formats and software suites are supported?

Accepted Answer

Our engineering design hub utilizes licensed Siemens NX (Unigraphics), PTC Pro/Engineer, Mastercam, AutoForm, and Autodesk Moldflow. We support seamless, lossless geometry interchange across all standard industrial formats, including STEP (.stp), IGES (.igs), Parasolid (.x_t), CATIA (.CATPart), SolidWorks (.sldprt), and AutoCAD (.dwg / .dxf).

Question 6

How do you safeguard client intellectual property (IP) and proprietary data?

Accepted Answer

Safeguarding client IP is a foundational operational principle. Before receiving sensitive engineering data, we execute a legally binding bilateral Non-Disclosure Agreement (NDA). Our engineering servers operate on physically isolated internal networks with role-based access logs and encryption. All CAD files remain strictly confidential and are securely archived or expunged upon project closure as contracted.

Question 7

What is the standard lead time from design approval to T0 injection trial?

Accepted Answer

Standard production lead time for medium precision injection moulds ranges between 25 and 35 working days. Large or complex automotive multi-cavity moulds typically require 40 to 50 working days. For urgent launch schedules or automotive pre-series validation, we provide an expedited fast-track engineering lane that compresses critical machining paths without compromising quality.

Question 8

What deliverables and data are provided during the T0/T1 trial phase?

Accepted Answer

Our in-house injection facility maintains multiple high-tonnage moulding machines for rigorous trial runs. On T0 trial day, clients receive uncut video recordings of the moulding process, comprehensive injection parameter logs, and full CMM inspection reports for critical dimensions. Physical samples are air-couriered within 24 hours via DHL/FedEx to your designated facility.

Question 9

Which international trade terms (Incoterms) and payment methods are accepted?

Accepted Answer

We possess independent import/export certification and operate under Incoterms 2020: FOB (Ningbo/Shanghai ports), CIF, CFR, EXW, and DDU/DDP for qualified regions. Standard settlement utilizes international wire transfers (T/T) staged as 40% upon order confirmation, 30% upon approved T0/T1 physical samples, and 30% balance prior to ocean/air dispatch. Strategic recurring partners can request customized trade credit terms.

Question 10

What packaging standards and ongoing technical support do you provide for exports?

Accepted Answer

All export mould cavities are sprayed with heavy-duty rust inhibitors, sealed with oil-proof protective wrap, vacuum heat-sealed in multi-layer barrier foil, and secured in ISPM-15 compliant fumigated solid timber crates. Every crate includes a complete spare parts package (ejector pins, springs, seals, water fittings) and a USB drive containing complete 2D mould drawings, 3D tool models, and CMM metrology certificates. We offer lifetime engineering support and remote/on-site commissioning.
