Precision Machinery
Filter elements, structural frames and machined tubes from Dongguan — batch-consistent precision metal components with surface treatment; registry verification pending.
Three product lines, one precision standard.
Precision Filter Elements
Cylindrical metal filter components in stainless steel or aluminium, produced in batches with jig定位 for dimensional consistency. Ports show machining marks consistent with CNC turning or precision forming. Used in fluid control, filtration and industrial processing systems. Specify material grade (304 / 316 stainless, 6061 aluminium), mesh rating or perforation pattern, and pressure rating.
Metal Structural Frames & Chassis
Rectangular metal frames and chassis components with mounting holes and clean-cut edges. Multiple units stacked in the product photo suggest batch production with consistent dimensions. Applications include equipment housings, rack frames and structural supports. Specify material, thickness, hole pattern and surface treatment (powder coat, anodize, raw).
Machined Metal Tubes & Nozzles
Single-piece precision metal tubes with reduced-diameter or threaded ends, shown with a uniform brushed or sandblasted surface finish. The hand-held presentation in the product photo highlights surface quality. Applications include fluid connectors, nozzles, heat exchanger tubes and structural tubing. Specify OD, wall thickness, length, end configuration and material grade.
What the registry confirms, and what stays open.
Three Product Lines, One Precision Standard
The three product photos show filter elements, structural frames and machined tubes — different geometries but a common thread: dimensional consistency, clean edges and deliberate surface treatment. This suggests a shop floor with multi-process capability (cutting, forming, drilling, finishing) rather than a single-operation specialist. For overseas buyers, that means one supplier for multiple part types.
Batch Consistency from Jig Fixturing
The filter elements in the first photo are arranged in a regular grid, implying jig or fixture use during production. This is the kind of detail that matters to a buyer specifying tolerances: it says the shop thinks about repeatability, not just one-off accuracy. Ask for the actual tolerance range (±0.05 mm? ±0.1 mm?) and the measurement method (calipers, CMM, optical comparator).
Surface Treatment Awareness
The machined tube in the third photo has a uniform brushed or sandblasted finish — not raw mill finish. This signals that the company cares about appearance, not just function. For European and North American buyers, surface finish is often specified alongside dimensions. Confirm what treatments are available in-house (brushing, sandblasting, anodizing, passivation, electropolishing) and which are outsourced.
Dongguan Location — Supply Chain Advantage
Dongguan sits in the heart of the Pearl River Delta manufacturing belt, ~100 km from Yantian Port (Shenzhen) and ~80 km from Nansha Port (Guangzhou). Logistics costs are low, supply chain response is fast, and the “Dongguan” address carries brand recognition with overseas buyers who know it as a manufacturing hub. Confirm the exact town/district for the factory page.
Registry Verification Pending
The USCC 91441900MAKAUU8Y7J passes the GB 32100 check-digit rule with a Dongguan (441900) prefix, confirming this is a legitimately registered entity. However, the full registry snapshot (registered capital, establishment date, insured staff, business scope text, risk records) could not be pulled via the Tianyancha API due to permission limits. A business license scan has been requested to complete the verification.
Zero Online Visibility — Verified by Search
Google (CN + EN), Bing, Baidu, 1688, Alibaba International and Made-in-China were all searched on 2026-10-17 with the company name, USCC and English name variants. No confirmed results were found. This is both a risk (no trust signal for buyers) and an opportunity (CMH factory page will be the first indexable presence).
What was checked — and what the check found.
The USCC check-digit passes with a Dongguan prefix, confirming this is a registered entity. The product photos show real precision metal components with batch consistency and surface treatment awareness. What is stated rather than resolved: the full registry details (capital, establishment date, staff count, business scope), the equipment list and tolerance specs, certifications held, and the exact factory address within Dongguan. What would close it: a business license scan, an equipment list with specs, a capability sheet with materials and tolerances, and 20+ product photos including inspection scenes.
A Dongguan precision metal shop, read off the photos and the record so far.
Dongguan Yulai Precision Machinery Co., Ltd. (Yulai Precision Machinery) is a precision metal components supplier based in Dongguan, Guangdong, China. The company produces filter elements, metal structural frames and machined tubes — three product lines that share a common standard of dimensional consistency and surface quality.
The product photos provided show batch-consistent filter elements arranged in a jig pattern, rectangular structural frames with clean-cut edges and mounting holes, and a machined tube with a uniform brushed or sandblasted finish. These visual signals suggest a shop floor with multi-process capability and attention to repeatability — the kind of operation that can serve overseas buyers who specify tolerances and surface finishes on their drawings.
Dongguan's position in the Pearl River Delta manufacturing belt gives the company access to a mature supply chain, low logistics costs and fast response times. The “Dongguan” address is recognized by overseas buyers as a manufacturing hub. Registration is confirmed via USCC check-digit verification; full registry details are pending a business license scan.
From registration to listing, on the record.
