A 100-120 kg powder bonding machine is the production workhorse for metallic powder coating plants that fill bonded powder orders of 500-1000 kg. The system joins a 350 L hot mixing chamber with a 1000 L cold mixing chamber, so operators can bond aluminum flakes and other metallic pigments onto resin powder at a controlled temperature, cool the batch quickly, and pack a free flowing metallic powder that keeps its sparkle through spraying. Chenxing Machinery builds this large hot and cold mixing system for coating powder makers, color houses, and extruder plants that run several bonding stations and cannot afford long stops during shade changes.
The machine fits inside the hot and cold mixing station program of the Chenxing factory range and connects cleanly with dosing and compounding equipment when the customer wants weighed pigment addition instead of manual scooping. Raw resin powder can be lifted by powder feeding machinery, which keeps the 350 L hot chamber topped up between batches without dust escaping into the workshop.
Metallic powder coating looks wrong when the flakes break, overheat, or separate from the resin carrier. The 100-120 kg unit avoids these faults by keeping the two mixing stages physically separate. The metallic pigment and the powder coating base go into the 350 L hot mixing chamber first. Hot water circulating through the jacket and friction from the blades raise the temperature to a window just below the resin softening point, and the aluminum flakes stick onto the softened resin particles. The bonded powder is then discharged into the 1000 L cold mixing chamber, where it is agitated and cooled before packing.
Temperature stays inside a safe window the whole time. The PT100 probe feeds readings to the PLC, which trims the water flow and blade speed instead of waiting for the operator to react. A nitrogen blanket purges the chamber before the cycle when the pigment is oxidation sensitive, and the automatic bonding detection system signals when the batch is ready. Operators simply wait for that signal, open the discharge damper, and move on to the next load.
For plants that want the bonded powder to feed into downstream processes, Chenxing also supplies extruder selection support and granule making machinery for the wider coating and compounding line.

A practical batch starts with the operator weighing 80-125 kg of resin powder and metallic pigment. The recipe is called up from the stored set, the one-key start button is pressed, and the hot mixer begins heating while the nitrogen blanket is set if the pigment needs it. The PLC follows the temperature curve, adds the pigment at the programmed moment, and holds the window until the automatic bonding detection signal arrives. The discharge damper then opens and the bonded powder falls into the 1000 L cold mixer, where the cooling curve pulls it down to packing temperature. Sieving and packing follow, and the powder plant support machinery section covers the screens and bagging stations that complete the line.
Color change between metallic shades is handled with purging powder. The hot chamber is emptied, the blades and damper clearance are checked, and the discharge chute is wiped down before the next recipe loads. Plants that run several shades per shift save real time because the automatic feeding systems keep the chamber full without manual lifting.
The 100-120 kg bonding machine belongs in coating powder plants that fill production orders of 500-1000 kg, metallic powder producers, and color houses running several bonding stations. It is the market mainstream model, and it suits paint-to-powder conversion projects where a factory replaces liquid paint lines with powder finishing.
The same metallic powder can feed architectural profile finishing, furniture coating, home appliance coating, and automotive coating lines. Chenxing supplies the surrounding machinery from the same factory: profile line equipment and profile finishing lines for window and door profiles, panel production machinery and marble panel equipment for flat surfaces, plus pipe machinery range, pipe plant solutions, PVC pipe plants, HDPE line solutions and HDPE pipe plants for pipe coating work. Field examples are listed on the field application examples page.
Chenxing Machinery treats each bonding unit as a configurable project, but the customization has clear limits. The chamber sizes, motor ratings, and the 350 L / 1000 L split are fixed for this capacity class. What can be changed is confirmed at enquiry: plant voltage (380V 50Hz 3 phase standard, other voltages on request), equipment color (RAL5013 blue standard, other RAL on request), discharge and conveying integration, dosing scales for the metallic pigment, extra sieving stages, and a finished powder packing station.
For factories planning a complete compounding hall, the machine links into plant layout guidance and project engineering support, where Chenxing handles layout, piping, and commissioning together. Line integration for reprocessing line support and specialty machinery projects can also be discussed at the same stage.
The 100-120 kg bonding machine is assembled under the same quality routine as the rest of the Chenxing production program, certified to ISO9001 and built to CE requirements for the European market. The chamber welding is checked before the water jacket is pressure tested, the PT100 probes are calibrated against a reference, and the inverter and PLC wiring are inspected before the panel is closed. Every machine runs a trial with aluminum flake pigment before shipment, so the bonded powder test result travels with the machine.
The Chenxing factory introduction page explains the workshop background, and the material transfer equipment range covers the conveyors that move powder between the mixing hall and the packing area.
Every 100-120 kg bonding machine leaves the Chenxing workshop after a full functional test with real powder batches. The system ships in several crates sized for standard containers, with export packing that protects the mixer shells, control cabinet, and pipework. Because this is a large hot and cold mixing system, on-site installation guidance is usually recommended, and the Chenxing team supplies a detailed layout drawing before arrival so the customer can prepare the floor.
The equipment documentation package covers wiring, maintenance, and recipe setting in English, and the workshop news page shows recent machine developments. Buyers can compare the Chenxing product catalog and the extended product listings before ordering, check any technical point against the installation question list, or send the 100-120 kg bonding machine inquiry directly for price and lead time.
The machine takes 80 to 125 kg per batch, with 100 kg as the typical working load. The 350 L hot mixing chamber and the 1000 L cold mixing chamber are sized for that window.
The hot mixing chamber is 350 L and the cold mixing chamber is 1000 L, with the cold mixer loading about 500 kg. This split is what makes the machine a large production bonding system rather than a trial unit.
A normal production run delivers about 300 to 400 kg per hour of bonded powder, depending on the pigment type, resin formula, and cooling time required.
The hot mixer applies the resin coat onto the metallic flakes at a temperature just below the softening point, and the cold mixer cools the bonded powder quickly so the flakes stay intact and the powder remains free flowing.
Aluminum flakes and most metallic effect pigments used in powder coating can be bonded here. The nitrogen protection blanket is standard, so oxidation sensitive materials are covered without an extra option.
A typical batch runs for about 15 to 20 minutes from resin loading to cold discharge. Several batches can be completed in a standard work shift, which supports the 300-400 kg/h output range.
Yes, the PLC touch screen stores up to 400 parameter sets, so customer colors and metallic shades can be recalled with one-key start. Color change is handled with purging powder and a quick wipe-down of the discharge chute.
The combined hot and cold mixing system needs about 8 m by 5 m with a height around 5 m, and the total installed power is about 80 kW. The standard supply is 380V 50Hz 3 phase, with other voltages available on request.
It works well beside profile and sheet lines because the coating plant can bond its own metallic powders instead of buying ready mixed material. The same factory can run the bonding machine, extrusion lines, and finishing equipment from one supplier.
