Choose a 400-ton melamine molding machine if your product line focuses on standard melamine tableware. It provides the optimal balance of cost, footprint, and operational efficiency.

Select a 600-ton melamine molding machine if you typically require for oversized trays, deep-compartment serving dishes, or bathroom equipments, like toilet seat covers.

How Tonnage Works in Melamine Compression Molding?

Melamine (thermoset) molding uses a hydraulic compression press to close the mold, apply heat, and hold pressure until the powder cures.

Clamping force (tonnage) must overcome the internal molding pressure acting on the projected area of the molded part plus runners.

As a manufacturer of melamine molding compound machines, Shunhao Machines and Moulds Factory recently received inquiries from one of our long-term cooperating customers regarding their selection of new melamine compress machines to expand their production lines. Due to our customer would like to explore new directions in hotel and house ware, we offer two options between 400 tons and 600 tons melamine compress machine for reference.

Here are technical parameters of 400 tons VS 600 tons of Shunhao melamine compound machine:

The tonnage of melamine molding machines is not necessarily better when it's larger; the optimal choice is to match it appropriately with the mold and product requirements.

FAQ

Q: Can a 600-ton melamine press produce small plates and bowls?

A: Yes. You can run small molds on a 600T press, but it consumes more floor space and energy. It's not cost-prohibitive if you already own it for large products, but buying a 600T only for small tableware is not economical.

Q: Will a 600T machine increase my production speed?

A: Not directly. Cycle time is determined by melamine cure time (typically 60–120 seconds depending on thickness), not clamping force. A 600T may let you run more cavities per shotif platen space allows, effectively increasing hourly output — but individual part cure time stays the same.

Q: Is higher tonnage always preferable?

A: No, the appropriate press tonnage should be matched to your mold size and product type, rather than simply the biggest available.

A 400-ton press is preferred by the majority of melamine tableware factories due to its lower power consumption and easier maintenance.
