High Quality Multi-Cavity Melamine Compression Mould for Tableware
Product Detail
Melamine tableware compression molds (also known as melamine molds) are precision molds specifically designed for high-temperature and high-pressure molding of thermosetting melamine resin. They are the core components of melamine tableware production lines.
Core Structure
l Cavity: Determines the outer shape of the tableware (female mold)
l Core: Determines the inner shape of the tableware (male mold)
l Mold Base: Upper and lower mold plates, used for installation and fixation
l Guiding System: Guide pillars and guide sleeves, ensuring precise mold closing
l Heating System: Built-in electric heating element/heating plate (150–180°C)
l Ejection System: Ejector pins, push plate, ejection mechanism
l Overflow Channel: Discharges excess material and controls thickness
Molding Principle
1. Feeding: Melamine powder is added to the preheated mold cavity.
2. Mold Closure and Pressurization: 15–30 MPa high pressure.
3. Heat Curing: 150–180°C, resin cross-linking and curing.
4. Ventilation/Pressure Holding: Air is removed to ensure density.
5. Mold Opening and Ejection: The cured product is ejected.
In summary, melamine compression molds are the core factor determining the precision, gloss, efficiency, and cost of tableware.
FAQ
Question1：What type of steel is used for the mold? What is its lifespan?
It is made of P20/718 mold steel with a hard chrome plating.
Under normal maintenance, its lifespan is 500,000 to 1,000,000 mold cycles. The chrome plating can be replated after wear and reuse.
Question2：How many cavities does a mold need? Can it be customized?
We can make 1-cavity, 2-cavity, 4-cavity, 6-cavity, etc., depending on the product size and the customer's hydraulic press.
Fully customized: We can open molds from drawings, samples, or 3D files.
Question3：What surface finishes are available?
High-gloss, matte, wood grain etching, stone grain etching, frosted, and other finishes are available.
Question4：How long does mold production take?
Usually 7-20 days depending on mold complexity.
Question5：How are molds packed for shipment?
Packed in wooden cases with anti-rust protection.
