Automatic Melamine Cup Forming Machine
HCE uses left and right hydraulic cylinders and side mold halves to extend the basic single-color hot-press process to three-dimensional products. The side molds define the outside form, while the main press closes from the vertical direction. This structure gives product designers more freedom for cups, vases, flower pots, shaped bowls and shaped buckets.
When the machine starts, the left and right mold halves close and the side cylinders keep them clamped. The operator manually loads melamine compound into the mold, then the main press rises to close the mold and apply vertical main pressure with degassing, platen heat and holding time. The side-cylinder design must resist the spreading force created by the main pressure; if the side mold halves are forced apart, excessive flash forms at the parting line.
HCE advantages for side-mold forming
- Left and right hydraulic cylinders close and clamp the side mold halves before the main pressing step.
- After manual loading, the main press rises, closes the mold and applies vertical main pressure.
- Proper side-clamping force resists the main pressure and helps prevent excessive flash from an opening side-mold joint.
- Cups, vases, flower pots, shaped bowls and shaped buckets can be developed from the product geometry and mold split.
Machine Functions and Molding Sequence
HCE uses the same basic heating, degassing and pressure-holding principles as a single-color melamine press, with the addition of left and right hydraulic cylinders and side mold halves. The side molds first close around the product form and remain clamped; the main ram then rises from below so side clamping and vertical compression work together in one molding cycle.
At machine start, the left and right hydraulic cylinders move both side mold halves toward the center and hold them clamped. Closing position, joint faces and clamping force directly affect the product shape and parting line.
After the side molds are secured, the operator manually loads melamine compound into the mold cavity. Charge weight and placement follow the product volume, wall thickness and available mold space.
After loading, the main press rises to close the mold and apply vertical main pressure. Platen heat, degassing and holding pressure then fill the cavity and complete thermoset curing.
Cylinder diameter, hydraulic pressure, mounting position and mold loading must be matched correctly. If vertical main pressure forces the side mold halves open, compound escapes through the joint and creates excessive flash.
HCE-80 to HCE-200 model range
Selection among HCE-80, HCE-100, HCE-150 and HCE-200 considers part size, charge weight, cavity count and daily output, as well as side-mold projected area, required force from the left and right hydraulic cylinders, vertical main pressure, daylight and unloading space.
These models suit smaller parts, lighter charges or lower cavity counts. Han Chang checks side-mold area and main pressing force to match the hydraulic cylinders and mold fastening method.
Greater main force, platen area and daylight support taller, wider or heavier shaped products and molds, while retaining practical space for side-mold movement and manual compound loading.
The side cylinders are not a simple auxiliary motion; they must keep both side mold halves clamped while the main press rises. Selection considers projected area, main pressure and the acceptable flash condition.

How HCE expands three-dimensional product design
Han Chang uses the product geometry, left/right mold split and vertical closing direction to match side-mold travel, hydraulic clamping force, main pressure, platen and daylight. Cups, vases, flower pots, shaped bowls and shaped buckets follow the same forming logic: the mold split and the load path must work together.
The side mold halves surround the cup body or container wall, and vertical main pressure completes the upper/lower closure. This suits deep products that cannot release cleanly from a basic two-piece vertical mold.
Curved bodies, narrowed openings and external shapes can use a left/right mold split to provide release space. The side molds remain clamped before vertical main pressure is applied.
Non-round profiles, raised patterns and special outlines can be divided among the side molds and upper/lower mold, giving designers more freedom than a flat-tableware mold.
The side-mold joint must stay closed throughout the main pressing cycle. When the cylinders and mold structure resist the spreading force, flash at the parting line is easier to control.
- Part drawings and three-dimensional geometry establish the split between the side molds and upper/lower mold.
- Side-mold dimensions, joint faces, travel, weight and cavity count establish hydraulic clamping force and operating space.
- Charge weight, wall thickness, vertical main pressure, flash requirement, output and voltage establish hot-press conditions and model size.
HCE delivery and maintenance support
On-site HCE checks follow the real production sequence: side-mold closing and clamping, manual loading, main-press rise, degassing, holding, opening and part removal. When flash becomes thicker, the first check is whether the side mold halves remain fully closed under vertical main pressure.
On-site personnel use the pressure gauge, control display and observed movement to check side-cylinder closing position, hydraulic pressure, left/right synchronization and any mold gap during pressure holding.
For excessive flash, the inspection compares vertical main pressure, side-clamping force, mold joint condition, charge weight and holding state to identify spreading or material overflow.
Applicable builds can use Mitsubishi PLC, Fuji Electric touch panel and Japanese-brand oil seals. Teams in Taiwan and Mainland China can support operation guidance, parts identification and maintenance from the delivery records.
CE certification is available according to the actual HCE specification and export project. Side-mold guarding, the manual loading area, electrical control and safety circuits follow the movement confirmed in the order.
Melamine Cup and Shaped-Product Molding Machine FAQ
What is the actual HCE production sequence?
After machine start, the left and right hydraulic cylinders close and clamp both side mold halves. The operator manually loads the compound, then the main press rises to close the mold and apply vertical main pressure with degassing, platen heat and holding time.
What do the left and right hydraulic cylinders do?
They close and lock the side mold halves so the product’s three-dimensional side form remains fixed during main pressing. Cylinder size, pressure, mounting position and mold load must all match the vertical main pressure.
Why does an opening side mold create excessive flash?
As the main press rises and applies pressure, material and cavity pressure create a spreading force on both side mold halves. If side clamping is insufficient or a joint gap opens, compound escapes through the parting line and produces excessive flash.
Which products can HCE produce?
Depending on mold design, HCE can produce cups, vases, flower pots, shaped bowls, shaped buckets and other single-color melamine products that require side mold halves to work with vertical main pressure. Final size and geometry follow the mold split and release direction.
How does Han Chang configure HCE?
Han Chang reviews the part geometry, side-mold projected area, mold joint, charge weight, vertical main pressure, cavity count, daylight and output to match the HCE model, left/right hydraulic cylinders and hot-press conditions.
