PRODUCTION PROCESS
PT. Pumarin is known as one of the reliable marble producer in Indonesia. In order to maintain this existence, the factory must produce the best quality products, the whole production process needs to be approached with patience, precision. dedication and professionalism

Through its’ dedication and primary material selection, the company wants to o turn each piece of raw material into a natural marble stone product that will remain as an investment with the feeling of elegance and style for years.

The whole process can be broken down in to the following stages:

• Mining
• Primary Selection
• Cutting
• Polishing
• Squaring
• Sorting Process ( QC)
• Packaging
• Waste Management System

MINING
Marble Block is taken from the rock beds in large blocks before being cut into more manageable sizes which are then transported to the factories.

PRIMARY SELECTION
Once the blocks arrive at the factories they are sorted into the color that they are expected to be produced. This is only the first step of determining the colour and the quality. Marble is a natural product, one will only be able to classify the color once the final cutting and final sorting process takes place.

CUTTING
At first, the block is classified by the shape and the size, and then cut by a gangsaw or block cutter into slabs. The large blocks are cut into slabs or strips depending on the machinery used.. There are two ways the blocks can be cut into slabs:
• Cross Cut: The block is cut along the bedding plane.
• Vein Cut: The block is cut against the bedding so that the bedding plane is revealed, which means that the veins are exposed


POLISHING
The slab is calibrated in order to make the surface smooth, even and straight flat, and also to achieve the desired thickness. After then, one or both sides of the slab will be polished.

SQUARING
After done with the polishing process, the slab basically is ready as finished goods, but if we need them in tiles or other sizes and shapes, we then cut the slab into the desired width, length, and shape. We call this process as the Squaring Process.

SORTING PROCESS ( QC )
The color and character of each marble tile will always vary one and another. To standardize the classification, we sort out the variation and quality into Premium Grade, Standard Grade and Semi Select Grade.

PACKAGING
The tiles are packed into high quality wooden crates and are prepared to be shipped to their different destinations. Each crate contains a different quantity depending on the product.

WASTE MANAGEMENT SYSTEM
The waste water from the production lines, will be collected in a waste tank prepared and periodically the residu / remenance of marble dust at the bottom of the tank will be allocated into a waste hardening process, whereas the water will be recycled to be re-used in the production.
