FAQS

Frequently Asked Questions About Our Integrated DFM, Moldflow, and Injection Services.

What is your maximum part size machining capability?

A: We specialize in machining high-precision plastic components with a maximum length of 400 millimeters. This enables us to optimize machine clamping force and reduce molding costs for our customers.

What is the typical lead time for mold fabrication and mass production?

A: Our lead time is generally 15 to 25 days, depending on the complexity. Once the sample is approved, mass production can be completed in as little as 7-10 days, helping you shorten your time-to-market.

A: Yes, we provide professional DFM (Design for Manufacturing) Analysis and Moldflow Analysis for every project. Our engineering team evaluates manufacturing feasibility and optimizes part geometry to prevent defects like sink marks or air traps. For all purchasing customers, these high-value engineering services are provided free of charge.

What if parts fail to meet specifications?

A: Quality Assurance:

Each part undergoes multiple verifications before shipment: trial production testing, quality inspection, and customer confirmation. Our quality process ensures products comply with agreed specifications, minimizing non-conformance risks.

After-Sales Handling:

In case of non-conformance, submit a claim request with inspection data, photos, or videos. Our quality team will review within 48 hours to identify root causes.

Resolution Options:

Based on the assessment, we will offer one of the following solutions:

  • Rework or Remake
  • Partial Refund
  • Credit Compensation

All cases are fully documented with inspection reports for complete traceability. We recommend customers retain original samples and relevant materials to expedite resolution. Each case is incorporated into our continuous improvement system to enhance service quality.

How long does it take to receive a quote for custom molds and parts?

A: Typically, we provide a detailed, transparent quote within 24 hours after receiving your 2D drawings or 3D CAD files (STEP, IGES, or X_T formats), including preliminary manufacturing feasibility advice.

Do you support low-volume production or rapid prototyping?

A: Absolutely. We offer flexible manufacturing solutions, including low-volume production and rapid prototyping via CNC machining or bridge tooling. Whether you need 100 pieces for market testing or 100,000 pieces for mass supply, we provide the same level of engineering support and quality control.
