Davantech offers three core manufacturing services from its ISO 9001:2015 certified factory in Dongguan, China: precision CNC machining (milling, turning, drilling, wire EDM), insert molding and overmolding of plastic components and cable assemblies, and full product assembly including testing and packaging. All three are available together under one roof, giving customers a single supplier for their complete production chain.
Davantech's factory is located in Zhangmutou, Dongguan, Guangdong Province, China — approximately 45 minutes from Shenzhen Bao'an International Airport and 60 minutes from Hong Kong International Airport. The facility covers over 5,000 square metres. Davantech also has a commercial office in Wevelgem, Belgium, serving European customers directly. You can reach us at sales@davantech.com or europe@davantech.com.
Yes. Davantech is ISO 9001:2015 certified. The certification covers the full production scope: CNC machining, injection molding, overmolding, insert molding, and product assembly. The certificate is available on request. Our quality management system governs every step from incoming material inspection through production to outgoing inspection and shipment documentation.
Yes. Factory visits are welcomed and encouraged for both existing and prospective customers. During a visit you can tour the CNC machining department, injection and overmolding lines, assembly area, and quality control lab. Our Chinese and Western project managers will guide you through each department and answer technical questions directly. Contact sales@davantech.com to arrange a visit and we will assist with logistics and accommodation recommendations in Dongguan.
Davantech signs a Non-Disclosure Agreement before any drawings or files are shared. Files are stored on internal servers with role-based access controls. Sub-contractors receive only the information needed for their specific operation and sign their own NDAs. Full assemblies are never exposed to sub-vendors. Davantech can also assist customers with patent and utility model applications in China to further protect proprietary designs.
Simple CNC parts and standard overmold assemblies receive a quotation within 24 hours. Complex multi-part assemblies or new tooling projects receive a quotation within 48 hours. Every quotation includes a free DFM review flagging any manufacturability concerns before production starts. Send your STEP files, drawings, material specification, surface finish, and quantity to sales@davantech.com.
Standard payment terms for first orders are 60% deposit before production and the balance before shipment. Net terms become available after an established order history. Invoices are issued in the name of the legal entity on the ISO scope. Bank transfer is standard; other payment methods can be discussed for repeat customers.
EXW and FOB are standard. DAP and DDP are available on request. For express delivery, Davantech ships via DHL, UPS, FedEx, and TNT — typically 3 to 8 working days to Europe or North America. Sea freight from Yantian port in Shenzhen takes approximately 6 weeks to Europe. Davantech can also ship on your own courier account if preferred. Shipment photos are provided before dispatch on request.
Chinese New Year (typically late January or February) and Golden Week (early October) cause factory closures of 1 to 2 weeks. Davantech plans ahead by pulling forward material procurement, finishing, and inspection for orders due around these periods. We inform customers of upcoming holiday impacts at the quotation stage and propose buffers where needed.
Davantech offers 3-axis and 4-axis CNC milling, conventional CNC turning, and Swiss-type sliding headstock turning for long slender parts. Additional operations include drilling, reaming, tapping, boring, grooving, threading, and knurling — all performed on the same machine centre to minimise setups. Wire EDM is available for precision profiles and hard materials. 5-axis milling is available through a qualified sub-contractor for complex geometries requiring it.
Standard tolerance is plus or minus 0.05 mm for general milling and turning. Precision features to plus or minus 0.02 mm are achievable on critical dimensions. Roundness to 0.01 mm is achievable on precision turned parts. Surface roughness Ra of 0.8 µm is achievable on finishing passes. All untoleranced dimensions default to ISO 2768-m unless otherwise specified on the drawing. GD&T is accepted per ISO 1101 and ASME Y14.5. CMM verification is available on request.
Davantech machines a broad range of metals and engineering plastics. Metals include aluminium alloys (6061-T6, 7075-T6, 2024-T3, 5052, 6063), stainless steel (303, 304, 316L), carbon and alloy steels (1018, 1045, 4140, 4340), brass (CW614N, C360), copper (C110, C145), and titanium (Grade 2 and Ti-6Al-4V). Engineering plastics include PEEK, POM (Delrin), Nylon PA6/PA66, Polycarbonate, PTFE, ABS, PMMA, and PVC. Mill certificates are available for all materials and linked to each job for full traceability. See the full materials guide for properties and grade selection.
Available finishes include sandblasting, brushing, polishing, and grinding. Surface treatments include anodizing (Type II clear and colour, Type III hard anodizing), powder coating (any RAL colour), electroless nickel plating, passivation (ASTM A967), zinc plating, black oxide, and PVD coating. All treatments are managed under the ISO 9001:2015 quality system. Thickness and adhesion are verified per batch. Critical bores and toleranced features can be masked before treatment to maintain dimensional accuracy.
There is no minimum order quantity for CNC machining. Davantech produces from 1 piece for prototypes through to millions of parts for volume production. Prototype series (1 to 20 parts), small series (20 to 500 parts), medium series (500 to 10,000 parts), and mass production (above 10,000 parts) are all accepted. Unit cost decreases with volume as setup and overhead costs are amortised across larger batches.
Standard prototype lead time is 3 to 5 business days for simple parts. Production lead time for CNC machined parts is typically 5 to 10 business days after order confirmation, covering material procurement, machining, inspection, and surface treatment. Complex parts or tight tolerance requirements may extend lead time. The estimated shipping date is confirmed at quotation stage.
Yes. First Article Inspection (FAI) reports are available for new parts, showing measured actual values against nominal for all toleranced dimensions. CMM reports covering critical-to-quality features are available on request. Material certificates (mill certs) confirming alloy composition and mechanical properties are linked to each job batch and available with every shipment. PPAP documentation at levels 1 to 3 is available for automotive and regulated industry customers.
When a drawing revision is received, Davantech logs the new revision, confirms the effectivity point, quarantines superseded drawings and programs, and labels any WIP or stock by revision. If the change affects cost or lead time, a revised quotation is issued before production continues. Customers are advised to submit ECOs as early as possible — changes after machining has started may result in material write-off costs.
DFM (Design for Manufacturability) review is a free engineering check performed on your drawing before production starts. Davantech checks wall thickness (minimum 0.8 mm for metals, 1.0 mm for plastics), tool access and depth-to-diameter ratios for deep pockets, tolerance feasibility for the specified material and process, thread geometry and undercut relief, surface treatment compatibility with toleranced features, and datum scheme for multi-setup parts. Any issues are flagged with proposed solutions before any cost is committed to tooling or machining.
Injection molding produces a single-material plastic part by injecting molten resin into a mold cavity. Insert molding places a pre-formed component — typically a metal contact, threaded insert, or PCB — inside the mold before injection, so the plastic encapsulates it in a single operation to create an integrated metal-plastic part. Overmolding injects a second material (typically a soft TPE or TPU) over an existing substrate — a rigid plastic housing, a cable jacket, or a metal component — to add grip, sealing, or strain relief. All three processes are available at Davantech.
The minimum order quantity for plastic injection molding and overmolding is 1,000 pieces. This minimum exists because mold tooling is produced for each project and the tooling cost must be amortised across the production run. For quantities below 1,000 pieces, CNC machining of plastic parts may be a more cost-effective alternative — Davantech will advise on the best process at quotation stage. Samples of 10 to 50 pieces can be produced from production tooling for customer approval before full production.
Lead times for a new injection or overmolding project follow these stages. Mold manufacturing: 30 to 45 working days for the production tool. First samples (T1): 2 to 5 working days after mold completion. Customer approval of samples: allow 5 to 10 working days for shipping and evaluation. Mass production: 14 working days minimum after sample approval. Overmolding production runs approximately 500 cycles per day. Simple single-cavity cable overmold tools can be completed in 14 days. Complex multi-cavity connector tools take 20 to 28 days.
Davantech molds a wide range of engineering thermoplastics and elastomers. Structural resins include ABS, ABS-PC blend, Polycarbonate (PC), Nylon PA6 and PA66, PBT, PPS, and PEEK for high-temperature applications. Overmold materials include TPE (SEBS-based), TPU, flexible PVC, LSR (liquid silicone rubber) for medical applications, TPE-V for automotive, and PUR for continuous-flex applications. Glass-filled and flame-retardant (UL94-V0) grades are available. RoHS, REACH, FDA, and USCAR-2 compliant materials are stocked and certified.
Davantech routinely produces overmolded assemblies to IP54, IP65, IP67, IP68, and IP69K ratings per IEC 60529. IP67 (1 m submersion for 30 minutes) is the most common specification for M12 sensor connectors, USB cables, and cable glands. IP68 (continuous submersion at manufacturer-defined depth and duration) is achievable with correct wall thickness, bore interference, and bond overlap design. For IP68 assemblies, 100% inline pressure decay testing is available as an alternative to submersion testing. IP69K (high-pressure hot washdown) is achievable with appropriate material selection and geometry.
Yes. Davantech can overmold onto customer-supplied cable assemblies, connector bodies, or plastic substrates. The substrate material must be confirmed before tooling begins to verify chemical bond compatibility with the selected overmold compound. Davantech can also manufacture the complete assembly in-house — sourcing the cable, producing the connector substrate by insert molding, and then overmolding the finished assembly — under one quality system.
The customer owns the mold tooling once the tooling invoice has been paid in full. Davantech stores and maintains the molds on the customer's behalf at no additional storage charge while orders are active. If a customer wishes to transfer tooling to another facility, Davantech will cooperate with the transfer process. Tooling is designed and built in Davantech's own tool room, giving full control over lead time, cost, and maintenance.
Standard testing includes IP ingress testing per IEC 60529, cable pull-out force testing per USCAR-2 or IEC 61169, bond peel strength testing, and 100% electrical continuity check. Optional tests include pressure decay testing (non-destructive alternative to submersion), flex endurance testing per IEC 60227, thermal cycling per IEC 60068-2-14, UV ageing per ISO 4892-2, and hi-pot dielectric withstand testing for high-voltage assemblies. Test results are documented and available with every shipment on request.
Davantech offers three types of product assembly. Mechanical assembly joins plastic and metal structural components using screws, press fits, snap fits, rivets, adhesive bonding, and ultrasonic welding. Electromechanical assembly combines electrical components — motors, sensors, switches, PCBs, and connectors — with mechanical structures, including wiring, crimping, and functional verification. Box build and final assembly covers complete finished product build including firmware loading, 100% functional and cosmetic inspection, custom packaging, and labelling.
The minimum order quantity for product assembly is 500 units. Prototype and pilot builds of 10 to 50 units are available before committing to volume production, using the same assembly process, quality system, and documentation as full production. The same engineering team manages the project from prototype through to volume ramp-up.
Yes. Davantech manages full or partial BOM sourcing from its audited supplier network in Dongguan and the surrounding Pearl River Delta region. Electronic components, fasteners, standard hardware, cables, PCBs, and connectors can all be sourced, inspected, and fed into assembly without the customer managing multiple suppliers. Customer-supplied (consignment) components can also be used alongside Davantech-sourced parts in the same order.
Quality control covers every stage. Incoming components are inspected against specification before entering production. In-line quality checks are performed at defined intervals during assembly. First Article Inspection is conducted on the first completed unit of every new job. 100% functional and cosmetic inspection is performed before packing. Full traceability records linking each finished product to its component batches and assembly operators are maintained and available on request. Testing options include functional testing, AOI, ICT, hi-pot, and pressure decay.
Yes — this is Davantech's primary differentiator. CNC-machined metal parts, injection-molded plastic housings, insert-molded connectors, and overmolded cable assemblies are all produced in Davantech's own factory and fed directly into the assembly lines. This eliminates inter-supplier logistics, reduces lead time, maintains quality control across the complete production chain under one ISO 9001:2015 quality management system, and gives the customer a single point of contact for the entire product.
Yes. Davantech configures output packaging to match the customer's market and logistics requirements. Options include retail packaging (printed cartons, blister packs, branded inserts), OEM-neutral boxes for distribution, bulk packing for B2B shipments, and Amazon FBA-compliant packaging. Custom labelling, barcode printing, serial number assignment, and multi-language documentation can be included in the packing station workflow.
Prototype assembly lead time is 1 to 2 weeks after components are available. Production assembly lead time is 3 to 6 weeks after order approval, covering component sourcing, inspection, assembly, testing, and packing. For products combining in-house manufactured components (machined parts, molded housings), the component manufacturing lead time runs in parallel with sourcing of external components to minimise total lead time.
