Our Automatic Weighing Machine For Melamine & Urea Molding Powder is dedicated auto batching equipment developed for thermoset molding workshops. Designed for melamine molding powder and urea‑formaldehyde UMC powder, it completes automatic feeding, precise weighing and quantitative discharging. Replaces manual weighing to eliminate human weight deviation, less flash, short‑shot and defective dinnerware / toilet‑seat parts. Built‑in PLC control system works seamlessly with 250‑ton, 300‑ton and 400‑ton melamine hydraulic presses, realizing stable continuous running for mass‑production lines.
Core Advantages & Main Product Structure
Core Advantages
- High‑Precision Weighing Performance: Adopts industrial high‑accuracy load‑cell sensors. Minimize weight deviation, lower reject rate caused by manual weighing mistakes.
- Reduce Labor & Raw Material Loss: Fully automatic cycle operation cuts labor cost. Reduce molding powder waste, improve overall production efficiency and factory profit.
- PLC + Touch‑Screen Intelligent Control: Store multiple product formulas, one‑click switch for different product weights. Multi‑language HMI interface, simple for workshop operators.
- SUS304 Contact Parts & Dust‑Sealed Design: Hopper, feeding chute and weighing bin use stainless steel. Anti‑corrosion, easy cleaning. Closed‑type structure suppresses powder flying and cross‑color contamination.
- Good Compatibility & Convenient Maintenance: Modular mechanical layout, easy inspection and spare‑part replacement. Can be retrofitted onto most existing hydraulic molding presses.
Main Product Structure
The machine consists of storage feeding hopper, vibratory feeding assembly, high‑precision weighing sensor unit, automatic discharging mechanism, pneumatic components and PLC electric control cabinet with touch‑screen HMI. Molding powder is delivered by vibration feeder into weighing bin. Once target weight is reached, system triggers automatic discharge toward mold cavity. Mechatronic integrated structure supports non‑stop repeated cycle for long‑time industrial operation.

Production, Quality Inspection & Packaging
Production Process
Machine frame adopts thick steel plate cutting and welding. All powder‑touching components are precision‑machined SUS304 stainless steel. Core electric and pneumatic components adopt well‑known industrial brands. Mechanical assembly and electric wiring follow standardized production workflow to guarantee stable mechanical‑electric coordination.
Quality Inspection
Each unit undergoes strict pre‑shipment testing: continuous cyclic weighing test, accuracy calibration, alarm function check, air tightness inspection and 8‑hour aging running test. Simulation test with real melamine / urea powder will be performed to verify practical performance. Operation manual, electrical schematic diagram and spare‑parts list are delivered together.
Packaging & Shipment
- Standard Export Packaging: Plastic film wrapping + solid plywood case, preventing collision damage during long‑distance sea transportation.
- Loading Port: Xiamen Port
- After‑sales Support: Remote video installation guidance, online operator training and long‑term spare‑parts supply.
Frequently Asked Questions
Q1: What molding materials is this automatic weighing machine compatible with?
A1: It is specially developed for melamine molding powder and urea‑formaldehyde UMC powder. It also supports other dry granular thermosetting molding compounds for similar compression‑molding processes.
Q2: What is the weighing range and accuracy of this auto batching machine?
A2: Standard weighing range is 50‑500g with accuracy ≤±2g. Both range and accuracy can be customized according to your product requirements.
Q3: How long is one complete feeding‑weigh‑discharge working cycle?
A3: Standard cycle time is within 10 seconds. The actual cycle will slightly change depending on material fluidity and target weighing weight.
Q4: Can this weighing machine be retrofitted to my existing hydraulic press?
A4: Yes. We can adjust discharging height, installation dimension and signal docking interface to match most 250T‑400T melamine hydraulic presses. Please provide your press size drawing for confirmation.
Q5: What material are the parts that contact molding powder made from?
A5: All direct‑contact parts including hopper, feeding chute and weighing bin adopt SUS304 stainless steel, anti‑corrosion and easy‑to‑clean.
Q6: What utilities do I need to prepare on‑site for machine running?
A6: Need AC220V/380V power supply and compressed air source of 0.4‑0.6 MPa. No extra complicated auxiliary equipment is required.
Q7: Does the machine support saving multiple product weighing formulas?
A7: Yes. The PLC control system can store groups of formula parameters. You can switch different product formulas on the touch screen with one click.
Q8: What is your pre‑shipment inspection standard for each machine?
A8: Every machine will pass 8‑hour aging running test, cyclic weighing calibration, air‑tightness test and alarm function check. Real molding powder simulation test is also carried out before delivery.
