Company scope
What the company makes
Zhejiang Haoxiang Precision Machinery Manufacturing makes chambers and machined parts for monocrystal, polycrystal and sapphire furnaces serving the semiconductor and photovoltaic industries. The factory is in Zhongguan, Deqing, Zhejiang.
Haoxiang names Hangzhou Jiangang Machinery Manufacturing as its predecessor and gives 2010 as the year that business started. The current legal company may carry a later incorporation date, so request the business licence if your supplier approval needs the exact record.
What Haoxiang sells is chamber work: bodies, covers, extension chambers and the assemblies around them. Furnace controls, process recipes and finished silicon ingots come from the furnace builder or the ingot producer. Graphite hot-zone parts that sit inside the chamber are bought separately from specialist suppliers.

Equipment portfolio
Start with the actual equipment
The entries below cover selected products and series from this manufacturer. Ask for the full catalogue if your project needs other models.
Furnace main chamber →
Haoxiang's furnace main chamber is a machined component for crystal-growth furnaces, listed in its furnace parts catalogue. You get the chamber body only. Order it against your own drawing and specify material, dimensions, seals and the leak test you need. The furnace,… [2]
Specifications & selection questions →Equipment Haoxiang lists
How Haoxiang machines, welds and checks a chamber
Large turning, boring and welding
Haoxiang lists 1.6-metre and 2-metre vertical lathes, a large boring machine, a 630 lathe, vertical and gantry machining centres, radial drilling, robotic laser cutting and argon-arc welding. Together these cover the main work on a chamber: the body, its openings, the flange faces and the welded seams. Send the finished drawing with your enquiry. Ask Haoxiang to mark which operations it runs in its own shop, which it sends out, and the tolerances it will hold on your part. Lathe size tells you the shop handles big work; the drawing review tells you whether your particular assembly fits. [1]
Stress relief, leak checks and surface checks
The same equipment list includes vibration stress-relief, a thermal imager, helium leak detection and dye-penetrant inspection. Helium testing finds leaks. Penetrant testing finds cracks and pores that break the surface. The website gives no leak-rate limit, test procedure or sample report for the listed chamber. Set those for your drawing, covering welds, seals and any reworked surfaces, and write them into the order so every delivered chamber arrives with its own test record. [1]
Catalogue entry and history
What the main chamber listing tells a buyer
A catalogue entry without dimensions
The main furnace chamber page sits beside entries for an extension chamber with horizontal adjustment and a furnace cover. It names the part and shows a picture. Material grade, wall thickness, vacuum rating, cooling layout and flange sizes are absent. Use the page to see the kind of part Haoxiang makes. For a replacement, send the equipment drawing and the existing interfaces. For a new design, specify the chamber together with the parts it joins, so the quotation covers a clearly defined set of components. [2]
Past work with crystal-growth equipment makers
Haoxiang says it has supplied crystal-growth equipment companies and names Jingsheng as a customer since 2012. If references matter to your approval, ask which comparable chamber design Haoxiang can document, whether that customer agrees to be named, and which manufacturing and test records will come with a new order. [1]
Project fit
Match the offering to your project
Haoxiang suits a buyer who already knows what the chamber has to do inside a crystal-growth or thermal-processing system and wants a shop to build it from drawings. Compare offers on machining, cooling, sealing and inspection. Choosing the furnace process and comparing ingot output is work you do with the furnace builder, since those figures belong to the whole furnace.
Confirm before ordering
- Material grade, drawing revision, dimensional tolerances and surface finish for the main chamber you order.
- The helium leak limit, the weld examination procedure and the inspection report supplied with the delivered part.
- Current business registration, a factory audit if your approval calls for one, and permission to name past customers.

Continue to sourcing requestBuyer questions
Does Haoxiang supply a complete monocrystal furnace?
Its main chamber entry is a component. A complete furnace needs its own supply scope, control system and process specification, which you buy as a separate package. [2]
What leak rate will a Haoxiang chamber meet?
Haoxiang lists a helium leak detector among its equipment and publishes no leak limit or test report for this part. Put the limit in your order and ask for a report for each chamber. [1]
Who signs off a replacement chamber before installation?
The furnace owner or the responsible equipment engineer approves the interface drawing and the inspection plan. Ask Haoxiang to mark its fabrication scope, sealing surfaces and inspection records on the drawing-based offer, and to state pressure, vacuum and thermal compatibility in writing.
