Tongling Jingda Special Magnet Wire Co. Ltd.

It earns by adding a processing fee on top of a pass-through metal cost. The price it charges customers is built from the market price of copper or aluminum ingot, agreed through point-price or average-price methods tied to published spot and futures exchange quotes, plus a separate fee for turning that metal into finished wire, and its own margin sits in that fee rather than in the metal price itself. Across every year of the financial history CompanyGraph has recomputed for it, that combination has produced a net profit.

CompanyGraph reads this company's growth as tied to physical production capacity: because it converts raw material into wire inside its own plants, growing output requires adding or running more of that conversion capacity rather than simply winning more orders, and how much it can run through is shaped by maintenance and by the supply of feedstock. Within that shape, the data CompanyGraph has recomputed shows revenue, gross profit and net income expanding together over recent years, with equity returns running high relative to the underlying gross margin, describing efficient use of capital inside a still-growing base. That growth has moved together with a rising pool of uncollected customer receivables, so part of the expansion CompanyGraph observes has taken the form of extended, not-yet-collected payment rather than cash already in hand.

Its own account describes what it converts as copper and aluminum rod, insulating varnish and other auxiliary materials, together with water and electricity, sourced from upstream metal and insulation processors. CompanyGraph separately maps this company as sitting downstream of a range of other industries that feed into it. The metal portion of what it sells is priced directly against published copper and aluminum spot and futures quotes, so a large part of its cost base tracks commodity markets it does not set.

In its own filings the company names automotive, electronics and industrial manufacturers, including General Motors, BYD, United Automotive Electronic Systems, Founder Motor, LG, Jingquanhua, Haiguang Electronics, Denso, Mitsubishi Heavy Industries and Panasonic, as customers it has long-term strategic relationships with. It describes downstream demand as spanning household appliances, industrial motors, power equipment, automotive and new-energy-vehicle motors, power tools, instrumentation, communications and electronics, and further sectors including military, aerospace, and photovoltaic and wind-power equipment. Its own account frames the company as a basic material supplier whose demand is set by those downstream industries rather than by its own choices.

CompanyGraph currently places this company inside a large group of producers that convert a raw material into a priced output under the same fixed-capacity economics, so the basic shape of its operations is a common one rather than a structurally rare position within what CompanyGraph can see. In its own filings the company points to its certifications, its research platforms, its part in drafting industry standards, and its long-standing customer relationships as what it says sets it apart, but whether rivals could replicate these is not something CompanyGraph has a way to confirm, since that depends on the capabilities of other companies that are not on file here.

The company's own account describes its customer relationships as stable because latent quality defects in magnet wire are not always detectable through routine sampling, so customers generally keep an established supplier in place unless a major problem occurs. It also states that it has signed long-term contracts with major customers, without disclosing specific terms, and that its products meet national and international certification standards that its own account frames as part of what qualifies it to supply those customers at all.

The broader pattern CompanyGraph tests producers of this kind against is that scale is limited by how much material a fixed set of plants can convert in a given period, shaped by maintenance downtime, by whether enough feedstock can be fed through at rate, and by whether the conversion fee stays wide enough above cost. This is a pattern CompanyGraph applies to this kind of producer generally, not a measurement of where this company's own capacity currently sits relative to that ceiling, which the materials reached do not state.

This company's own account describes its pricing as split into a pass-through metal cost and a separate conversion fee, with the metal portion tied to published copper and aluminum markets. That same split is also where the exposure sits: its results depend on keeping that fee wide enough above cost, and on the conversion-spread pressure that CompanyGraph's pattern for this kind of producer names as a common failure mode, rather than only on how much wire it sells. This is CompanyGraph's own reading of a disclosed pricing mechanism, not a risk the company itself has flagged in the materials reached.

The pattern CompanyGraph tests conversion businesses like this one against is pressure on the spread between input cost and conversion fee, and on whether enough feedstock can be run through at rate. This company's own account confirms the first part directly: it prices the metal component of what it sells against published copper and aluminum spot and futures quotes, so its economics are tied to commodity markets that move independently of its own operations and that it does not set.
