The PLC Automatic Melamine Tableware Edge Grinding and Polishing Machine is designed for the finishing stage after melamine compression molding. It automatically removes flash, rough edges and visible parting seams from molded tableware, providing a more efficient alternative to repetitive manual grinding.
The machine combines PLC control, touchscreen operation, adjustable grinding heads and multi-angle sanding in one finishing system. Different settings can be used for different product profiles, allowing manufacturers to process a broader range of tableware on the same equipment.
Typical products include:
Depending on product dimensions and shape, processing capacity is approximately 1,200–2,400 pcs/hour, making the equipment suitable for medium and large melamine tableware production facilities.
After compression molding, tableware can have excess material around the rim or parting line. The machine performs several finishing operations automatically:
Automating this process helps manufacturers achieve more consistent edge treatment across large production batches.
A PLC + touchscreen control system manages the grinding process and allows operators to change processing parameters for different products.
Adjustable settings include:
When production changes from plates to bowls, trays or other tableware, the relevant parameters can be adjusted according to the new product.
The adjustable sanding mechanism is suitable for more than conventional flat-edged tableware.
It can accommodate:
This flexibility is particularly useful for factories manufacturing multiple tableware series instead of a single standardized product.
Typical production capacity reaches:
Actual throughput varies according to:
The automatic process provides a practical way to increase post-molding finishing capacity.
The flexible pressure system maintains controlled contact between the grinding components and the tableware edge.
Its main benefits include:
Controlled pressure is especially important when processing decorative melamine products where the original surface appearance needs to be maintained.
Adjustable fixtures and replaceable sanding components allow the machine to handle different product specifications.
It is suitable for production involving:
The setup can be adjusted when moving from one production batch to another.
Edge grinding produces fine processing dust, so the machine is designed with an industrial dust extraction connection.
It can be integrated with:
This supports better dust management and a cleaner grinding area.

DONGXIN can configure the machine around the customer's actual tableware specifications and existing factory conditions rather than limiting the equipment to one standard product.
Fixtures can be adapted for different tableware geometries, including:
The appropriate fixture helps keep each product correctly positioned during automatic grinding.
Grinding configuration can be matched to:
This allows the equipment to serve factories that frequently change between different product series.
Standard options include:
Electrical specifications can be configured according to local factory standards before production.
Machine configuration can also be evaluated according to:
This helps match the finishing equipment to the output of the customer's existing molding operation.
The dust extraction interface can work with:
The final arrangement can be selected according to workshop layout and production conditions.
Suitable for:
The machine removes molding flash and smooths the outer rim after hydraulic compression molding.
Suitable for:
Adjustable grinding heads allow the system to follow curved edges and deeper rim profiles.
Suitable for:
Fixture and grinding settings can be adapted to different tray dimensions and edge structures.
The machine can also be configured for:
The appropriate fixture should be selected according to each product's dimensions.
The machine is suitable for manufacturers producing large quantities of:
Automatic finishing helps maintain a more uniform edge appearance throughout larger commercial orders.
In addition to melamine dinnerware, the machine can process suitable thermosetting molded products such as:
The actual configuration should be confirmed according to product structure and material.
Before manufacturing, DONGXIN confirms:
These details are used to determine the grinding and fixture configuration.
The main mechanical assemblies are then prepared, including:
The control system is installed and configured through:
Grinding heads and fixtures are adjusted according to the target products. Key setup items include:
Sample products can be used to evaluate:
The working parameters are then adjusted according to the actual product structure.
Repeated operating cycles are used to evaluate:
Before shipment, the machine is checked for:
Mechanical inspection focuses on:
Electrical inspection covers:
Grinding performance is evaluated through:
The machine is also operated continuously before shipment to confirm stable performance under normal working conditions.
Standard machine packaging:
Additional export protection can be arranged when required, including:
The Automatic Grinding Machine is normally installed after hydraulic compression molding.
A typical melamine tableware manufacturing sequence is:
DONGXIN can also provide supporting equipment and melamine tableware molds according to the customer's production requirements.
