We are 100% a direct manufacturer, not a trading company, agent, or reseller. XJHMFG operates a 15,000+ sqm injection molding production facility in Zhangzhou, Fujian, China — we own every machine, mold, and tool on-site.

You can verify this at any time. We welcome factory audits, in-person visits, and live video tours. Just contact us to schedule — no appointment required for qualified buyers.

Our factory is located in Zhangzhou, Fujian Province, China — approximately 90 minutes from Xiamen Gaoqi International Airport (XMN). We can arrange airport pickup for visiting buyers.

We welcome in-person factory audits and site visits at any time. If travel isn't possible, we also offer live video factory walkthroughs via WhatsApp or WeChat. Contact us to schedule →

Our facility covers 15,000+ sqm and houses 10+ automated injection molding machines ranging from 50-ton to 1,200-ton clamping force. All machines are equipped with robotic arm handling for unmanned 24/7 operation.

We also operate an in-house CNC precision engraving center, a dedicated mold-making workshop, a temperature-controlled raw material warehouse, and a QC inspection station — all under one roof.

We maintain strict internal quality management procedures aligned with ISO 9001 manufacturing standards. We also supply RoHS and REACH-compliant material grades for buyers requiring compliance documentation for EU and regulated markets.

For specific certification requirements relevant to your industry or destination market, please contact us and we'll confirm exactly what documentation we can provide.

We export to 20+ countries across North America (USA, Canada), Europe (Germany, UK, France, Netherlands and others), Southeast Asia (Singapore, Malaysia, Vietnam), the Middle East (UAE, Saudi Arabia), and Australia.

Our team has extensive experience with international trade documentation, customs requirements, and global freight logistics — so working with us overseas is straightforward regardless of your location.

XJHMFG has been operating as a direct injection molding manufacturer in Zhangzhou, Fujian for over a decade. We have served 100+ clients globally and currently support ongoing supply relationships with buyers across multiple continents.

We're happy to share client references or case studies relevant to your industry — just ask when you send your inquiry.

We stock and process 50+ engineering resin grades. Common materials always in stock include: PP, ABS, PA6, PA66, PA66+GF30, PC, POM, TPU, TPE, PBT, PC/ABS, and more.

Specialty grades such as PEEK, LCP, PEI, and reinforced compounds are available via 3–5 day regional procurement. If you have a specific material spec, just mention it in your inquiry and we'll confirm availability immediately.

Our standard production tolerance is ±0.05mm — suitable for most functional assemblies, snap-fits, and mating parts. For general cosmetic or non-critical parts, ±0.10–0.15mm is typical.

Tight tolerances of ±0.02–0.03mm are achievable for high-precision applications such as gears, sealing surfaces, and optical components — these require an engineering review during DFM to confirm feasibility for your specific geometry and material.

We offer the full SPI surface finish range: SPI A1–A3 (high gloss / mirror finish), SPI B1–B3 (semi-gloss / satin), SPI C1–C3 (matte), and SPI D1–D3 (textured / sandblast). Custom EDM grain textures are also available.

The appropriate finish is applied to the mold cavity during tooling — so there's no additional finishing operation on the molded part. Specify your required finish on your drawing or during the DFM review.

Every production batch goes through a three-stage QC process:

1. First-Article Inspection — the first shots of every run are measured against drawing dimensions before full production begins.

2. In-Process Checks — operators perform dimensional spot-checks and visual inspection at regular intervals throughout the run.

3. Final Inspection — 100% visual inspection of all finished parts before packing, with AQL-based dimensional sampling for critical features.

Batch traceability records are maintained so any issue can be traced back to specific production parameters.

We mix color masterbatch in-house against your Pantone code, RAL number, or a physical color chip you supply. Each batch uses the same formulated masterbatch and is evaluated under standardized lighting conditions before production starts.

For critical color applications, we recommend providing a physical reference chip rather than relying solely on a Pantone code, as screen-to-material color translation can vary. First-article color samples are always sent for your approval before mass production.

Yes. We support overmolding — molding a second material over an existing substrate. Common combinations we produce include ABS + TPE (rigid shell with soft-touch grip), PP + TPR (for seals and handles), and PC + TPU (optical device covers).

Overmolding requires two separate molds (one for the substrate, one for the overmold) and an additional production step. Let us know your application and we'll recommend the right material pairing and quote accordingly.

Yes — T1 trial samples are a standard part of every new mold project. After the mold is built, we run first-shot samples and send them to you physically for dimensional, functional, and visual evaluation. We don't proceed to mass production until you approve.

For existing catalog-style products (parts we already produce), we offer physical samples for qualified buyers — you cover shipping costs only. Contact us to request samples of specific parts.

Absolutely. We work with buyers at every stage of product development. If you have a hand sketch, reference photo, napkin drawing, or even just a verbal description, send it to us and our engineers can create an initial 3D model for your review.

Alternatively, if you have a physical sample or a competitor's product you want to replicate or improve upon, we can reverse-engineer it into a manufacturable design. There's no cost for the initial consultation — just reach out.

DFM stands for Design for Manufacturability — an engineering review of your part design to identify anything that would make it difficult, expensive, or impossible to injection mold correctly.

Our engineers check for issues like insufficient draft angles, wall thickness inconsistencies, undercuts requiring side actions, weld line locations, and gate placement — and provide specific recommendations to fix them before tooling begins.

Yes, the DFM review is completely free and typically completed within 24 business hours of receiving your file. There's no obligation to proceed with an order afterward.

We take IP protection seriously. Before reviewing any design files, we sign a Non-Disclosure Agreement (NDA). Your designs are stored securely, never shared with third parties, and never reused for other clients.

The mold we build for you is 100% your property — we keep records of this clearly documented. We do not produce your parts for any other buyer without your written authorization. If you wish, we can also store your molds under lock with restricted access logging.

You own the mold, 100%. Once you've paid for the tooling, it legally belongs to you. You can request it to be shipped to you or to another factory at any time.

We keep the mold in our facility for production convenience and maintain it at no extra charge during your active supply relationship with us. But we make clear from day one: the mold goes wherever you decide. We earn your business through quality and service, not by holding your tooling.

For new custom parts requiring a new mold, our MOQ starts at 500 pieces. This covers the economics of setting up, running, and inspecting a dedicated production batch.

For repeat orders on existing molds, there's no strict minimum — we can run as few as 200 pieces depending on the part. For very large parts or specialty materials, we'll advise the practical minimum based on the setup cost.

We do not require large upfront volume commitments. Many of our buyers start with a small validation batch and scale up from there.

If the T1 samples don't meet your dimensional, cosmetic, or functional requirements, we revise the mold at no additional charge for reasonable engineering changes within the original design intent. We then run T2 (or T3) trials and send new samples until you're satisfied.

We never start mass production without your explicit written approval of the samples. This is a core commitment, not a policy that depends on circumstances.

Yes, mold modifications are common. Adding steel to a mold (making a feature smaller or removing a protrusion) is relatively straightforward and low cost. Removing steel (making a cavity larger or adding a boss) is also possible but more involved.

Minor changes — like adding a hole, adjusting a rib depth, or tweaking a snap-fit — can typically be machined into the existing mold. Major geometry changes may require a new cavity insert, which we'll quote separately. We'll always recommend the most cost-effective approach for your specific change.

Simply submit an RFQ with your part drawing (or description), estimated quantity, and material preference. A real engineer reviews every inquiry — we don't use auto-response pricing calculators.

For standard parts, we typically respond within 4–8 business hours. For complex custom parts requiring a full DFM review, expect a response within 24 business hours. The quote will include itemized mold cost, unit price, lead time, and material spec — no bundled or hidden figures.

Mold cost is a one-time tooling investment, not a per-order charge. Once the mold is paid for, you own it and it's used for every subsequent production run at no additional tooling cost.

Mold cost depends on: part size and complexity, cavity count (single vs multi-cavity), steel grade selected, and specific features like side actions or lifters. After your DFM review, we quote mold cost and unit price separately so you can clearly see both components.

Our standard payment terms are:
New mold projects: 50% deposit before tooling starts, 50% balance before shipment of first production batch.
Repeat production orders: Typically 30–50% deposit with balance before shipment, depending on order value and relationship history.

We accept payment via T/T (bank wire transfer), and for established clients, net payment terms may be available. Please discuss your preferred arrangement when placing your inquiry.

Once we provide a confirmed quote, prices are fixed for that order. For long-term supply agreements, we typically lock in pricing for a defined period (e.g. quarterly or annually) so you can plan costs predictably.

Significant raw material price swings — such as those caused by global resin supply disruptions — may require pricing reviews, but we always notify you in advance before any adjustment and never change confirmed order pricing mid-run.

Yes — unit price decreases with higher quantities due to fixed setup cost amortization and material purchasing leverage. We structure our quotes with tiered pricing so you can see the per-unit cost at different volumes (e.g. 1,000 pcs / 5,000 pcs / 20,000 pcs).

For annual volume commitments or blanket orders with scheduled releases, we can negotiate further pricing advantages. Let us know your projected annual volume when inquiring.

Standard quotations are valid for 30 days from the date of issue, subject to raw material price stability. If resin prices fluctuate significantly within that period, we'll notify you before the quote expires.

If you need a quotation held longer — for example, to get internal purchase approval — just let us know and we'll work with you to extend or lock in pricing where possible.

Lead times depend on order type:

New custom part (new mold): 22–35 days total — 15–20 days for mold + T1 approval, 7–12 days production, 3–5 days packing and shipping prep.

Repeat order (existing mold): 7–12 days production, plus freight transit time.

Prototype / small batch: 11–17 days with rapid tooling option.

All lead times begin from drawing approval and deposit receipt, not from first inquiry. We maintain large material stock so there's no procurement delay built in.

We primarily ship on FOB Xiamen terms — major international ports are within close proximity to our Zhangzhou facility. You handle freight from there using your preferred forwarder.

We also accommodate CIF (Cost, Insurance, Freight) and DDP (Delivered Duty Paid) for buyers who prefer a door-to-door arrangement. If you have a preferred freight partner, we can work with them directly.

Yes. We offer a full range of packaging options: individual poly bags, foam inserts, custom inner cartons, retail-ready packaging, and standard export outer cartons with your labeling.

For branded packaging — with your logo, product name, or retail artwork — we work with local printing and packaging suppliers to produce inserts, labels, and boxes to your spec. Lead time and minimum quantity for custom packaging will be quoted separately.

Yes — we prepare a complete set of standard export documents with every shipment: commercial invoice, packing list, certificate of origin, and bill of lading. We can also provide MSDS, material certificates, and RoHS/REACH declarations as needed.

We have experience shipping to 30+ countries and are familiar with common documentation requirements for the USA, EU, UK, Australia, and Southeast Asia. If your destination country has specific import requirements, let us know in advance.

Yes — for repeat orders on existing molds, we can often prioritize production and compress lead times significantly depending on current machine capacity. For new mold projects, rush tooling is available at a premium (typically 30–50% additional lead time reduction).

If you have a specific deadline, contact us immediately with your required ship date and part details. We'll give you an honest assessment of what's feasible and quote accordingly — we don't overpromise.

If parts arrive defective, out-of-spec, or incorrect — and the issue is attributable to our production — we take full responsibility. Our standard resolution is replacement production at no cost, prioritized in our schedule.

To process a claim, please send us: photos of the issue, affected part quantity, and the specific defect description. We'll respond within 24 business hours with a corrective action plan. We ask that you report quality issues within 30 days of receipt for us to initiate a claim.

Between production runs, molds are cleaned, lubricated, inspected for wear, and stored in our dedicated mold storage area with rust-prevention treatment. We track the shot count for each mold to anticipate maintenance needs before they become production problems.

Routine mold maintenance — cavity cleaning, ejector pin lubrication, cooling channel flushing — is performed at no additional charge as part of our ongoing supply relationship. Major repairs or refurbishment would be quoted separately.

Reorders are simple. Just send us a message — via email, WhatsApp, or WeChat — with your part number or order reference and the quantity you need. We retrieve your approved process sheet and mold records, confirm material availability, and issue a production schedule.

For repeat orders on in-stock materials, production typically begins within 1–2 days of deposit. Most reorders ship within 7–12 days. We keep all tooling, approved sample records, and production parameters on file indefinitely.

You'll be assigned a dedicated account contact who handles your project from inquiry through production and delivery. This person has direct access to our engineering and production teams — so you're not communicating through layers of intermediaries.

We're reachable via email, WhatsApp, and WeChat during business hours (Mon–Sat 8:00AM–6:00PM CST). WhatsApp is monitored outside business hours for urgent production updates. Response time is typically under 2 hours during working hours.

Yes, and we actively encourage it for buyers with regular demand. A blanket order or annual supply agreement allows us to reserve production capacity, pre-purchase materials at better rates, and provide priority scheduling for your runs throughout the year.

Benefits include: locked-in unit pricing, shorter lead times on call-offs, and a more predictable supply chain on your end. If you have a forecast — even a rough one — share it with us and we'll structure a proposal that works for both sides.
