What We Manufacture
Five equipment families covering the full induction chain — melting, power conversion, heating, vacuum processing and the auxiliary equipment that keeps them running.
Melting Furnaces
Coreless induction melting furnaces for steel, iron, copper and aluminium — steel-shell, aluminium-shell and dual-track, with hydraulic 95° tilting.
7 product lines →Medium Frequency Power Supplies
KGPS thyristor parallel-resonance and IGBT series-resonance inverters from 100 kW to 2,500 kW, with constant-power tracking and full protection. Larger ratings built to order.
3 product lines →Induction Heating Systems
Through-heating and surface-hardening lines for billets, bars, tubes and finished parts, with closed-loop temperature control and automatic handling.
5 product lines →Vacuum Furnaces
Vacuum and controlled-atmosphere furnaces to 3,000 °C for superalloys, hard metals, graphite purification and advanced ceramics.
4 product lines →Auxiliary Equipment & Spares
The supporting equipment and consumables that decide furnace uptime — cooling towers, hydraulic stations, water-cooled cables, capacitors and refractory linings.
4 product lines →Dual-Track Melting: Never Stop for a Lining Change
Two furnace bodies share one power supply through an interlocked switching cabinet. You melt on one body while the other is relined, cooled or held on standby — changeover takes under two minutes. For a foundry running two or three shifts, the recovered production usually repays the difference inside the first year.

Read MoreAbout Us
ForgeLink Induction Systems has manufactured medium frequency induction melting and heating equipment in Weifang, Shandong Province since 1998. Furnace bodies, coils, hydraulic systems and power supply cabinets are all built in our own works, and every system is assembled and run on load before it is dismantled for shipment.
Export contracts, documentation, logistics and overseas after-sales are handled together with Shanghai Linkster International Trade Co., Ltd., so an international buyer deals with one English-speaking team from enquiry through to commissioning and spare parts.
What Overseas Buyers Get
Importing a melting plant is a project, not a purchase. These six commitments are written into every export contract we sign.
Built to your grid
Voltage and frequency are specified at order — 380 V/50 Hz, 400 V/50 Hz, 415 V/50 Hz, 440 V/60 Hz or 480 V/60 Hz — with the matching rectifier transformer where required. No on-site improvisation.
Full-load test before shipment
The complete system is assembled and run on load in our works. You receive the test report, and you or your appointed inspector are welcome to witness it.
Seaworthy export packing
Fumigated timber crating with moisture barriers and desiccant, a container loading plan, and the complete document set: invoice, packing list, bill of lading, certificate of origin and insurance.
Installation and commissioning on site
Our engineers travel to your plant, supervise installation, install and sinter the first lining, commission on your own charge material and stay until the plant produces to specification.
Operator and maintenance training
Charging practice, melting procedure, lining monitoring, routine maintenance and fault diagnosis, delivered on your equipment with an English manual your team keeps.
Spare parts for the life of the machine
A two-year spares kit is priced in the original quotation, and every part is cross-referenced to your machine serial number so a later order is a part number, not a photograph.
From Enquiry to First Heat
A six-step project process with one named engineer accountable from the technical brief through to operator training.
- 01
Technical brief
We collect your alloy, target output per hour, working hours per day, grid voltage and frequency, and available floor space. Nothing is quoted until those six answers are on paper.
- 02
System design & layout
Our engineers return a furnace capacity and power recommendation, a plant layout drawing, a transformer and cable schedule and a cooling-water heat balance — normally within 3 working days.
- 03
Quotation & scope of supply
A line-by-line scope: what is included, what is by others, what the two-year spares kit costs. Payment terms, Incoterms and delivery are fixed at this stage, not negotiated later.
- 04
Manufacturing & factory test
Build progress is reported with photographs at defined milestones. Before shipment the complete system is assembled and run on load in our own works, and you or your inspector are welcome to attend.
- 05
Export packing & shipping
Seaworthy packing with fumigated timber, moisture barriers and desiccant. We handle the container plan, export declaration, certificate of origin and full document set for your customs clearance.
- 06
Installation, commissioning & training
Our engineers travel to your site to supervise installation, install and sinter the first lining, commission the system on your own charge material and train your operators and maintenance team.
Tell Us What You Melt
Alloy, target output per hour, working hours per day and your grid voltage are enough for us to come back with a capacity recommendation, a plant layout and a firm quotation — normally within three working days.

Sizing guides, technology comparisons and operating practice from our engineering team — written to be useful whether or not you buy from us.
Buyer Guide
How to Choose Induction Melting Furnace Capacity and Power
The sizing mistake that costs foundries the most money is buying the furnace they can afford instead of the one their pouring cycle needs. Here is how to work it out.

KGPS vs IGBT Induction Power Supply: Which One Should You Buy?
IGBT is newer, but newer is not the same as better for every duty. A practical comparison of thyristor and IGBT medium frequency power supplies for buyers.

Induction Furnace Lining: Installation, Sintering and Life
Lining life varies enormously between foundries running identical furnaces. Almost all of the difference is installation practice and the sintering curve.
