Hengda Furnaces

长兴恒达炉业有限公司 states that it designs and manufactures industrial furnaces and heat-treatment equipment, with installation and inspection among its services. Its product list also includes quenching, sintering, annealing, ageing and cleaning equipment. [1] This profile examines its brazing routes rather than assuming every listed furnace suits the same project.

The supplier’s aluminium examples are automotive applications. They establish upstream heat-exchanger production relevance, but no reviewed source confirms a construction-machine OEM contract, a particular excavator cooler or a finished cooler for sale. Bring your own approved assembly requirements.

The HB table repeats HB-70-12 for two different working-size rows. Its application sentence contains unclear wording. Ask for a controlled specification and corrected application statement before quoting that route; neither issue is silently edited into a definite claim here.

These are procurement inputs, not a completed Hengda installation survey. The published NB line lengths range from 28.5 to 37.7 metres; service space, loading arrangements and external utilities still need a project drawing. Do not reserve a factory bay from the catalogue length alone.

Decide what a satisfactory trial must demonstrate before placing an order. Supply representative parts, identified alloy/filler/flux, fixtures and joint requirements. Agree the sample identity, loading condition, recorded cycle and inspection method, including who supplies parts and who judges the result.

The homepage’s “99.5%” first-pass claim has no reviewed test protocol, sample population or part specification. It is not used as a guaranteed yield. Likewise, an advertised customer name does not replace permission-cleared project evidence for your order.

The official footer gives credit code 91330522670267759B, the same code in the business-registration record, and the same Lincheng Qiaonan development-area location in Changxing. [4] The imported record states incorporation on 21 December 2007. The site describes an earlier furnace factory; the predecessor relationship is supplier-stated, without reviewed transfer records.

The introduction’s design, technical and sales staff counts are undated. They do not establish current staffing or audited production capacity. Request the project design lead, fabrication resources and subcontracted work actually assigned to your line. No current quality certificate, independent factory audit or export service coverage was established in this review.

Before visiting or ordering, confirm the contracting entity, current factory entrance and destination support arrangements.
