Melamine Tableware Molding Machine
HCB is Han Chang’s standard press series for melamine bowls, plates, trays, cups and general thermoset tableware. The range covers small trial molds through multi-cavity production.
For tableware work, tonnage is only one part of the decision. Mold size, vent stroke and platen temperature are just as important because they show up directly in gloss, flash and demolding.
HCB production advantages
- Vertical compression and hydraulic holding pressure suit general tableware and multi-cavity molds.
- Degassing count, time and distance are adjustable for different powder charges and product depths.
- Cast-iron upper seat, middle seat and lower cylinder base support platen alignment during long runs.
- The HCB range runs from 37 to 800 tons for different mold sizes and daily output targets.
Machine Functions and Molding Control
HCB combines vertical hydraulic compression, adjustable multi-stage degassing, platen heat and holding pressure. The settings can be matched to powder, part thickness and cavity layout to control gloss, edges and demolding in daily tableware production. In production, the PLC links slow mold approach, degassing count, holding time, platen temperature and opening position into one cycle. When a mold or compound changes, operators can adjust from an established recipe instead of rebuilding every setting from the beginning.
The hydraulic cylinder presses upward. Slow approach and slow initial opening reduce mold shock, while fast travel shortens non-pressing time.
Up to 99 degassing cycles can be set, with adjustable time and travel for different powder charges, depths and cavity layouts.
Platen heat cures the powder while hydraulic pressure holds density and shape, affecting gloss, edges and release.
Pressing, degassing, holding and opening can run from saved settings, giving each shift the same starting recipe.
HCB model range and production advantages
The HCB range runs from 37 to 800 tons, covering small mold trials, general tableware production, heavy molds and multi-cavity output. Han Chang matches the model to mold envelope, projected area, daylight and heating capacity.
For smaller tableware, lower cavity counts, new molds and short production runs. The compact platen and daylight range keeps mold changes, cleaning and manual unloading practical, making these models useful for developing stable settings for new tableware programs.
A common production range for bowls, plates, cups and trays. Platen area, hydraulic holding pressure and adjustable degassing suit common production molds while balancing multi-cavity output, operator access and routine mold changes.
For larger platens, heavier molds, more cavities and higher daily output. The larger frame, platen and daylight support heavy molds and greater projected area, with room to plan multi-cavity tools, preheating transfer and material-handling equipment.

How Han Chang matches HCB to the mold and output
Han Chang uses projected area, cavity count, mold dimensions and daily output to match tonnage, platen size, daylight and heating capacity, giving the press the pressure, venting, access and operating space required for production.
Platen size, daylight and stroke follow the mold envelope, while the cast-iron upper seat, middle seat and lower cylinder base support long pressing runs.
Total pressure follows projected area and cavity count; adjustable degassing releases gas from different powder charges, thicknesses and cavity layouts.
Heater capacity and holding time work with charge weight so the powder cures with controlled density, gloss and shape.
HCB can be arranged around daily output, preheating, manual work or automation while keeping practical access for loading, cleaning and unloading.
- Part drawings, sample photos and planned cavity count connect the product to pressure and platen size.
- Mold dimensions, weight, daylight and compound data connect the mold to machine space, heating and degassing.
- Charge weight, daily output, voltage and floor space connect the project to power and operating layout.
HCB machine diagnosis and after-sales support
For HCB pressure, heating, degassing or opening issues, Han Chang can review the control screen, alarm record, pressure gauge and machine-action video.
Review holding pressure, degassing sequence, platen temperature, automatic cycle and sensor signals. The service review connects the exact action where the symptom appears with the saved parameters and molded-part condition, separating hydraulic, heating, sensor and mold-related causes.
Applicable builds can use Mitsubishi PLC, Fuji Electric touch panel and Japanese-brand oil seals, subject to the confirmed machine specification. Component makes and model numbers are confirmed for the order and recorded in delivery documents, giving maintenance teams a clear basis for spares and electrical service.
Both teams can assist with operation, online checks, parts identification and maintenance follow-up. Remote review first confirms the control display and machine action. When an on-site visit is needed, the Taiwan and Mainland China teams can continue from the same diagnosis record.
CE certification is available according to destination, machine specification and agreed document scope. Safety circuits, guarding and electrical documents are aligned with the ordered scope so export inspection, delivery records and the actual machine configuration remain consistent.
Melamine Tableware Molding Machine FAQ
What products are normally made on HCB?
HCB is used for melamine bowls, plates, trays, cups and general thermoset tableware. Projected area, cavity count and mold weight determine the model size. Degassing and holding settings can be matched to part thickness, compound behavior and cavity layout, allowing one HCB line to support a broader tableware program as production grows.
Can an existing mold be used on HCB?
Han Chang reviews mold dimensions, weight, daylight, stroke, heating method and removal direction against the HCB platen and movement before recommending the installation method. The review also covers mold fastening, heater connections and the working space for cleaning and unloading. Any adapter or mold-side modification can then be identified before installation.
Why does melamine molding need degassing?
Heated powder releases trapped air and volatile gas. Correct degassing count, time and travel reduce air marks, flash and uneven curing. HCB allows as many as 99 degassing cycles, but the production setting is selected from compound response and part appearance; the objective is controlled gas release, not simply the highest count.
When is a high-frequency preheater useful with HCB?
For heavier charges, thicker parts or higher output, preheating improves powder flow and the starting point of curing before the charge enters HCB. Because a heated charge must reach the mold promptly, preheater power, equipment position and HCB cycle timing are planned together to preserve the useful heating effect.
How does Han Chang select an HCB model?
Part, mold, compound, charge-weight and output data allow Han Chang to match tonnage, platen, daylight, degassing, heating and automation to the production requirement. Han Chang converts the information into a recommendation for pressure, platen, daylight, heater capacity and operating arrangement, then explains the practical trade-offs between HCB model sizes.
