Xiao Wu has sold CNC cutting inserts for three years, and there was one thing he could never quite figure out: why is it that among factories that all "do metal cutting," some walk away the moment they hear the price, while others will pay three times as much for a box of milling cutters? He later broke the downstream market apart on Tianxia Gongchang and finally understood where the problem was — customers aren't buying "tools," they're buying "the ability to cut this material to this precision." Different machined materials and different precision requirements put the tool selection logic, the unit-price range, and the cost of switching suppliers on completely different lines. Once you re-tier the market along this dimension, it becomes obvious at a glance which of the 148,000 downstream factories are worth chasing hard and which should just be covered with volume sales.
148,000 Downstream Factories Aren't One Market
I pulled up the full downstream picture for CNC cutting tools on Tianxia Gongchang: nationwide, real factories doing metal-cutting work that need to buy inserts, milling cutters, drills, taps, and carbide tools add up to 147,908. That number looks big at first glance, but once you break it into sub-pools, the picture changes completely.
The largest block is auto-parts manufacturing, at 69,075 factories. It's the highest volume, but the buying logic in this pool is mass-production style: monthly consumption of the same insert model is stable, the price-comparison cycle is short, and Tier-1 suppliers have already locked up the big accounts. What Xiao Wu can typically win here are low-price, high-volume orders with limited margin.
Machining and metal products (including precision parts, hardware, and stamped parts) — 46,685 factories — is the mid-tier mainstay where Xiao Wu now spends most of his time. This pool is large in scale and diverse in workpiece materials — the same factory might be running aluminum alloy this month and take on a stainless-steel job next quarter. Tool demand shifts with the workpiece, so purchasing stickiness is higher than in auto parts, but the cost of switching suppliers isn't especially high either — you have to rely on technical service capability to hold the relationship.
Mold manufacturing — 26,237 factories — is the direction Xiao Wu has been focusing on breaking into recently. Mold steel hardness is generally above HRC 50, and finishing requirements are high, so ordinary carbide tools simply can't keep up — you have to move to CBN (cubic boron nitride) or diamond-coated tools. The unit price is 5 to 10 times that of an ordinary insert, but switching suppliers requires customers to redo process validation, so the switching cost is high, and once you're on the approved list, repeat purchases are stable.
Machine-tool manufacturing — 9,532 factories — follows different logic from the other three: machine-tool makers are themselves downstream users of cutting tools, but they're also a supporting channel — some machine-tool makers bundle and recommend a tool brand together with the machine. Getting into this channel can bring in a batch of indirect customers. But the machine-tool makers' own direct purchase volume isn't large — this is a customer type where channel value outweighs direct-sales value.
| Downstream sub-pool | Factory count | Typical machined material | Tool demand tier | Sales strategy |
|---|---|---|---|---|
| Auto-parts manufacturing | 69,075 | Carbon steel, cast iron, aluminum alloy (mass production) | Standardized inserts, volume sales | Volume distribution, price-driven competition |
| Machining / metal products | 46,685 | Diverse: mixed steel, aluminum, copper, stainless steel | Mid-tier, shifts with the workpiece | Mid-tier mainstay, technical service builds stickiness |
| Mold manufacturing | 26,237 | High-hardness mold steel (HRC 50+), beryllium copper | High-end: CBN, diamond coating | High unit price, strong certification barrier, stable repeat purchases |
| Machine-tool manufacturing | 9,532 | Cast iron, structural steel (for machining the machine itself) | Low-to-mid, mainly channel value | Channel partnership, indirect customer generation |
Mold Factories Are the Real Battleground for High-Hardness Tools
Xiao Wu used to think "mold factories are too hard to get into" — the price negotiation cycle drags on, the owner wants a trial, wants samples, and it takes two months back and forth before you even know whether there's an order. He later shifted his thinking: getting into mold factories is hard because he wasn't treating "the tool's technical barrier" as his ticket in — he was only treating it as a bargaining chip.
Mold machining has one characteristic — high workpiece hardness, small machining allowance, and strict precision requirements, so switching tool brands on the same toolpath can directly affect surface finish and dimensional tolerance. This means that once a mold factory has validated a given tool's cutting parameters, it won't easily switch brands. Xiao Wu's standard move now when approaching a mold factory is: bring cutting-parameter data first (recommended cutting speed, feed rate, and coolant method for the corresponding mold steel grade), then propose a free trial cut on one workpiece and let the result speak. This is more than twice as efficient as going straight to price negotiations.
Another advantage of CBN and diamond-coated tools: there still aren't many domestic brands making this kind of tool, so customers' options for comparison shopping are inherently limited, and pricing power sits with the seller. This is completely different from the "compare three quotes, take the lowest" logic in the auto-parts segment.
A Different Map: Where Machining and Mold Factories Are Located
Xiao Wu's original travel routes followed the auto-parts map — Taizhou in Zhejiang, Suzhou in Jiangsu, Chongqing. But the map for the machining mainstay pool and mold factories differs noticeably from the map for auto-parts downstream. According to Tianxia Gongchang data, the city distribution for each sub-pool is as follows:
CNC Cutting Tools → Machining / Metal Products (Mid-Tier Mainstay)
46,685 nationwide
- Leading cities: Suzhou, 2,520; Wuxi, 2,385; Dongguan, 2,297; Cangzhou, 2,042; Shanghai, 1,913; Ningbo, 1,622; Shenzhen, 1,402; Qingdao, 1,178
- Leading provinces: Jiangsu, 8,113; Guangdong, 6,951; Shandong, 5,988; Zhejiang, 5,864; Hebei, 5,014
- Note: Suzhou and Wuxi are the two densest machining cities — a single trip can cover a large number of customers
CNC Cutting Tools → Mold Manufacturing (High Hardness, High Unit Price)
26,237 nationwide
- Leading cities: Dongguan, 1,147; Cangzhou, 1,019; Taizhou (Jiangsu), 735; Tianjin, 693; Wuxi, 677; Xuchang, 652; Changzhou, 614; Weifang, 545
- Leading provinces: Jiangsu, 3,872; Shandong, 3,388; Hebei, 3,093; Guangdong, 2,824
- Note: Dongguan is the country's densest mold-factory city, and Cangzhou is a major mold hub in North China, with an overlapping route with machining customers
CNC Cutting Tools → Machine-Tool Manufacturing (Supporting Channel)
9,532 nationwide
- Leading cities: Taizhou (Zhejiang), 461; Suzhou, 385; Dongguan, 352; Ningbo, 331; Cangzhou, 331; Foshan, 314; Wuxi, 279
- Note: Taizhou (Zhejiang) is the densest machine-tool city, with high channel-partnership value; Wuxi and Suzhou overlap with machining customers and can be visited along the same route
This map gives Xiao Wu a direct takeaway: Suzhou, Wuxi, and Dongguan are three cities with high-density distribution across all three customer types — machining, mold, and machine-tool — making them the highest-ROI travel destinations overall. Cangzhou is an easily overlooked North China node — 2,042 machining factories and 1,019 mold factories, together more than 3,000 potential customers concentrated in a single prefecture-level city, which makes the per-customer cost of a trip quite low.
Different Machined Materials Call for Different Ways to Find People
Tiering customers by material is the ranking method Xiao Wu currently finds most useful — it maps more closely onto actual sales actions than tiering by industry.
Aluminum-alloy machining shops: high tool consumption, frequent tool changes, short purchase cycles, and sensitivity to tool life and cutting stability. These are volume customers, well suited to long-term framework agreements, and price needs to be competitive — but response speed on service is the key to retention: if a tool breaks or a dimension drifts, a supplier that can't resolve it overnight gets replaced quickly. Aluminum-alloy workpieces make up a high share in both auto parts and machining, making this the main battleground for standardized inserts.
Stainless steel / titanium alloy machining shops: high cutting difficulty, short tool life, and strict requirements on matching coating to substrate material. These shops are usually willing to pay a higher unit price to reduce tool wear, making them genuine buyers of mid-to-high-end tools. On Tianxia Gongchang, precision machining shops with 50+ insured employees, and factories making aerospace parts or medical-device parts, show a noticeably higher share of stainless-steel and titanium-alloy workpieces — worth listing separately for visits.
Superalloy / cemented-carbide machining shops: few in number, but each tool purchase is high in value. These shops are usually concentrated within the supply systems for aviation, nuclear power, and shipbuilding. The entry bar is high, but once you're in, the cost of switching tools means customers rarely change suppliers.
High-hardness mold-steel machining shops: meaning mold finishing above HRC 50. As noted above, CBN and diamond tools are the standard here, price sensitivity is far lower than for ordinary carbon-steel machining customers, and this suits a sales model built around a high unit price, low frequency, and strong service lock-in.
How to Actually Do This on Tianxia Gongchang
Xiao Wu's standard process now is: log into Tianxia Gongchang, filter by industry category for "machining" or "mold manufacturing," add the target city (say, Suzhou or Dongguan), then apply a second filter on insured headcount — a machining shop with 20+ insured employees usually has a stable production line and dedicated purchasing staff; a mold factory with 10+ insured employees is most likely a genuine, active manufacturing entity rather than a shell company.
Compared with the tens of thousands of results you'd export from a certain lookup service or Qichacha by keyword — "business scope includes tools/machining" — what Tianxia Gongchang filters out are factories genuinely doing cutting work, not shells that registered this business scope without actually producing. This difference is critical in real-world visits — working through an unfiltered list of generic results gets you an effective rate under 30%, and the travel cost gets wasted on the road.
Tianxia Gongchang's factory profiles let you see the registered address, contact details, and the trend in insured headcount directly. A factory whose insured headcount has risen over the past year is most likely expanding production — a new production line usually means a new tool-purchasing window, and going in to talk at that point is far easier than waiting until the line has stabilized and looking for an opening later.
Salespeople selling mold tools can layer on one more filter: run the industry filter separately for "plastic molds," "die-casting molds," and "precision stamping molds," because different mold types require very different tool materials — knowing in advance what kind of mold a company makes lets you prepare more precisely targeted technical materials before the visit.
Check These 5 Things Before You Head Out
- What's the factory's main workpiece material — carbon steel, aluminum alloy, stainless steel, or mold steel? — The material determines which tool series to pitch; don't show up with the wrong samples.
- What precision level does the workpiece require — rough-cut volume parts or precision-fit parts? — Precision determines the unit-price range, and also whether you should be doing technical selling or volume distribution.
- Who's the current supplier, and how long have they worked together? — A factory that's had a stable relationship for over two years with no expansion is hard to break into short-term; prioritize factories that are expanding a line or starting a new business line.
- Has insured headcount risen over the past year? — A rise means the factory is expanding production, and a new production line is usually the best window for switching tool brands.
- Is the purchasing decision-maker in the purchasing department or is it the process engineer? — At mold factories and precision machining shops, the process engineer often has more say than purchasing in tool selection, so make sure you're talking to the right person.
Use Tianxia Gongchang to Screen This List
After splitting 148,000 downstream factories into four tiers, here's how to work them:
- Auto parts (69,075): the main volume battleground, fiercely price-competitive, suited to a standardized-insert distribution logic — not the priority segment for high-unit-price tools.
- Machining / metal products (46,685): the mid-tier mainstay, diverse materials, where technical service capability is the core of building stickiness; Suzhou and Wuxi are the two densest cities.
- Mold (26,237): the real battleground for high-hardness tools, where CBN/diamond tools carry a high unit price and a high cost of switching suppliers; Dongguan and Cangzhou are the key travel destinations.
- Machine tools (9,532): channel value outweighs direct-sales value; prioritize discussing bundled partnerships; Taizhou (Zhejiang) is the densest city.
The list Tianxia Gongchang filters by industry + city + insured headcount is the only customer-finding method Xiao Wu currently uses — after filtering out shell companies, the effective visit rate is more than double what an unfiltered list gives.
A Tianxia Gongchang membership costs ¥768/year, covering 4.8 million+ real manufacturing enterprise profiles, unlimited filtering and export, with business-registry and insurance data synced weekly. That works out to ¥2.1 a day for the year — cheaper than one outdated industry directory, and you can re-filter anytime by city, scale, or industry.

The next increment of growth for CNC cutting tool sales doesn't come from running through the same auto-parts customers one more time — it comes from recognizing that "machined material + precision" are the real axes for tiering customers. Most tool salespeople haven't seriously worked the 26,237 mold factories, because the impression that they're "hard to get into" has held them back — but behind that hard-to-open door are exactly the customers genuinely willing to pay a premium for tool performance. On Tianxia Gongchang, the addresses and contact details for these factories can be filtered out right now.
