Melamine Plate, Bowl and Tray Hot Press Setup
Melamine plates, bowls and trays may use the same material family, but they do not behave the same inside the mold. Product depth, rim design, projected area, cavity count and demolding direction all change the hot press setup.
This guide organizes the product-shape questions buyers should prepare before asking Han Chang to evaluate a melamine tableware molding machine or production line.
Plate Molding Setup
Flat and shallow plates usually focus on surface gloss, rim consistency, flash control and uniform pressure across the mold. Platen size, heating area and mold fit should match the largest plate in the product family.
Bowl and Deep Product Setup
Bowls and deeper products need careful review of mold depth, material placement, air release, demolding direction and product deformation risk. Daylight and stroke become more important than they are for shallow products.
Tray and Compartment Product Setup
Large trays and compartment trays require attention to projected area, cavity layout, heating uniformity and operator handling. Their size can affect platen selection even when the material weight is not high.
Venting, Holding and Surface Quality
Flash, bubbles, uneven gloss and color shift can come from mold venting, powder condition, preheating, pressure holding and demolding. Shape-specific trial production helps separate machine limits from mold or process issues.
Inquiry Checklist
- Plate, bowl or tray drawings and maximum size.
- Product depth, rim shape and expected thickness.
- Mold cavity count, mold dimensions and mold weight.
- Single-color, double-color or decorated surface requirement.
- Expected daily output and available operator workflow.
Buyer FAQ
Can one melamine machine make plates, bowls and trays?
It can be possible if tonnage, platen size, daylight, stroke, heating area and mold handling match the full product range. The decision should be made from actual mold data.
Why do deep bowls need special review?
Deep products can create different air release, material flow and demolding conditions, so daylight, stroke and mold design become more important.
What should be tested before mass production?
Check surface quality, flash, bubbles, dimensional stability, demolding marks, color consistency and whether the cycle is repeatable.

What buyers should observe in the videos
Watch the feeding method, mold closing movement, degassing action, pressure holding, demolding and finished tableware shape. These details help confirm whether the project needs a single-color press, a double-color setup, high-frequency preheating or a customized line layout.
Video FAQ
- What information should be prepared after watching the videos?
- Prepare product photos or drawings, tableware diameter and depth, target material, mold cavities, expected output, voltage, factory layout and whether the line needs preheating or automation.
- Can the same machine support every melamine product shape?
- No. Plates, bowls, trays, cups and spoons can require different mold depth, opening height, platen size, venting design and pressure settings, so the machine should be selected by product geometry and mold conditions.
