FAQ / Buyer’s Guide
Find practical answers about drawings, tooling, materials, sample approval and packing. Confirm the final technical and commercial details with your project quotation.
Three things to prepare before you inquire.
Your drawing
2D / 3D files, mating parts, critical dimensions and the current revision.
Your application
What the component does, its environment, preferred resin and visible surfaces.
Your production plan
Target quantity, sample needs, timing and required documentation.
Answers from Haixiang.
What is your core business?
We provide a complete, end-to-end manufacturing solution. Our core business includes custom injection mold design and fabrication, alongside high-volume plastic injection molding mass production, seamlessly taking your project from concept to finished product.
Do you offer secondary operations?
Yes, we offer comprehensive secondary operations to complete your parts. These include surface finishing solutions like custom painting, silk-screen printing, EMC, pad printing, laser engraving, electroplating, sandblasting, and ultrasonic welding, ensuring your components are fully market-ready.
What is the maximum part size and weight you can manufacture?
With injection molding machines ranging from 80 to 380 tons, we can produce a wide variety of parts. We manufacture everything from small parts to large industrial housings weighing up to 1 to 2 kilograms (with dimensions up to approximately 600mm x 500mm).
Do you accept low-volume manufacturing (prototyping) before mass production?
Yes, we fully support your testing phase. We accept low-volume runs to help you validate product designs, test market viability, and ensure functionality before you commit to mass production. Additionally, if your required product quantity is around 100 pieces, we highly recommend our vacuum casting services as a fast and cost-effective solution.
Drawings & Quotation
What information helps you review a custom part?
Send a drawing or model, application, preferred material, target quantity and any important dimensions, surface or assembly requirements. If a detail is undecided, explain what the part needs to do.
Which drawing formats can I upload?
The website inquiry accepts STEP, STP, IGES, DWG, PDF and ZIP files, up to 50 MB per file. Include a dimensioned drawing when tolerances or cosmetic requirements need explanation.
Can I inquire before my design is finished?
Yes. Share the current concept and explain which decisions are still open. The team can discuss the material and manufacturing route; a final quotation depends on a clear agreed scope.
How are lead time and order quantity agreed?
They depend on part geometry, material, tooling and the proposed production plan. Include your target dates and quantity so they can be addressed in the project quotation.
Materials & Surface Finish
Which material should I choose?
Begin with operating conditions, impact, stiffness, appearance and assembly needs. Haixiang’s material guides cover ABS, PC, PC/ABS, PA / Nylon, PP, PBT, PMMA, POM, ASA, GPPS and PEEK; the actual grade follows the application review.
Can I specify a custom color or texture?
Provide a color code, physical reference or agreed sample and identify the visible surfaces. Color, gloss and texture should be reviewed with the resin, geometry and selected finishing method.
Can parts include printing or other secondary operations?
Discuss required printing, painting, assembly or ultrasonic welding with the part brief. Suitability depends on the material, geometry and intended use.
Does a material name establish regulatory compliance?
No. Specify the exact declarations, test reports or application requirements you need. The selected grade and supporting evidence must be confirmed for your order.
Tooling & Samples
What is checked before mold manufacturing?
Review geometry, release direction, ribs, bosses, joining faces, inserts and important cosmetic zones. The selected resin and production quantity also inform the tool concept.
How do I approve a sample?
Compare the sample with the drawing revision, mating parts, critical dimensions and the agreed appearance reference. Record required changes before confirming the production reference.
Can I request molded-in inserts or two materials?
Share the insert drawing or the intended material interface. Insert molding, overmolding and 2K molding need a part-specific review of placement, support, compatibility and tooling.
Who owns the tool and what maintenance is included?
Tool ownership, storage, maintenance and modification terms should be stated in the tooling quotation or order agreement. Confirm them before commissioning a mold.
Quality & Delivery
How are inspection priorities agreed?
Identify critical dimensions, cosmetic faces, fit requirements and the records needed. The agreed drawing and approved sample guide incoming, in-process and outgoing checks.
Can I request quality or material documents?
Tell the team which certificates, declarations or test records your company or market requires. Current documents and their scope must be confirmed for the actual application.
How should I specify packing?
Explain how the parts will be handled after arrival. Include surface protection, part separation, grouping, labeling and carton or crate requirements where relevant.
Who should I contact about a project?
Contact Wang Xuehai, Sales Manager, at 342608774@qq.com or +86 136 5046 0601 (phone / WhatsApp). The company is based in Linqing City, Shandong Province, China.
