To all of you involved in purchasing building materials or renovating factory buildings, I’m sure you’d like to understand exactly what the production process for Gaoyi resin roofing tiles entails. From the arrival of APVC raw materials at the factory to the finished product leaving the kiln, the core processes consist of three stages: compounding, extrusion molding, and cooling and quality inspection. The parameters for each step are clearly documented and verifiable.
What raw materials are used to make Gaoyi resin roofing tiles?
APVC ResinIt is the main component, accounting for more than 60 percent, and is combined with stabilizers, lubricants, and color masterbatch in the specified proportions. Gaoyi uses importedAPVC ResinBlended with domestically produced materials to balance low cost and good weather resistance; the formulation is fine-tuned once every quarter.
On the surface, the mixing process appears to be a routine operation; however, even slight variations in mixing time or the temperature of the mixture can cause bubbles or uneven coloring in the tiles produced later on. In our workshop, the mixing machine runs for a full forty minutes, and we maintain the mixture temperature within a range of seven to nine degrees. These parameters were finalized only after conducting hundreds of batch tests.
How Is Temperature Controlled in Extrusion Molding?
During the heating process, the extruder is divided into three sections, and the temperature rises gradually. When the material enters the second section, it is precisely within the melting range. This stage is the most critical; if the temperature difference is too great, the raw material will burn; conversely, if the temperature difference is too small, plastification will be insufficient.
The precision of the mold clearance directly determines the uniformity of the roof tile’s thickness. During the production process of Gaoyi Resin Tiles, the mold lip components underwent extensive and repeated fine-tuning. The final finished tiles have a thickness tolerance of no more than 0.2 millimeters. This is precisely what sets them apart from their competitors.
How Are Gao Yi Resin Tiles Inspected?
After the roof tiles are removed, they must first be inspected under an ultraviolet light to check for silver streaks and curled edges. They are then cut into small sections to undergo ball-drop impact tests and cold-bending tests. Only when all these tests meet the standards are the tiles permitted to be stacked and sent to the warehouse for storage.
We also have to select one batch of products each week to use forAccelerated Aging Test, The changes in color and the brittleness indices must be incorporated into the national standards, checked against each item one by one, and recorded item by item; this procedure must not be omitted under any circumstances. Finally, all data must be archived and preserved.
The parameters recorded for each process step allow for traceability, which is the core logic underlying the entire process. At the same time, this forms the foundation of product consistency.
