1985
Mr. Zhou led a team of four to start Great Wall Foundry in Wuzhou, Guangxi, China. With a 200 kg furnace, the foundry started with melting metal scraps into steel blocks and sold them to bigger steel makers as melting material.
1987
Observing the boom in China's economic reform, Great Wall Foundry started to produce manganese jaw liners up to 500 kgs that were popular among quarries in Guangdong province.
1992
In order to increase its manufacturing capacity, Great Wall Foundry moved to a new location at Zhongshan, Guangxi, China. A new foundry was built with four one-ton furnaces, and large jaw liners up to 3 tons were made to meet the demand in the market.
1998
Great Wall Foundry started to produce cone crusher liner parts, as a result of cone crushers becoming more and more common in crushing plants.
2002
Great Wall Foundry began to build its own R&D team, focusing on metalogy. Later the foundry successfully
started producing castings with manganese contents of 18%.
2007
Great Wall Foundry expanded its foundry in 2007, and a new machine shop was built to accommodate the demand of machined parts for export markets.
2008
After years of study and research, Great Wall Foundry perfected its techniques of "Clean Melt" and "Die Casting with Sand Layer". These concepts are still the key characteristics of the parts the foundry manufactures. Especially when later new products with a higher manganese content were developed, "Clean Melt" provided a great advantage on the productions of castings with 21% and 25% manganese contents.
2009
With
the "Clean Melt" and "Die Casting with Sand Layer" technique, Great
Wall Foundry successfully caught the attentions of some industrial
leaders in the crusher manufacturing. The foundry started to supply
OEM wear parts for partners of leading crusher manufacturers. Its
international sales team, MnSteels, was formed and began its first
step to the international market.
2018
Great Wall Foundry started its new plant project in Fuchuan, Guangxi, China. The plant is due to open in late 2020.
Our foundry is located in Hezhou, Guangxi, China, 450 kms away from Yantian, Shenzhen.
Guilin Liangjiang International Airport (KWL), us about 200kms from our foundry. Taking the high speed rail from Guangzhou to us (Zhongshanxi Station) is about 2 and half hours, and from Guilin to us (Zhongshanxi Station) is about 1 hour.
Room temperature.
– All castings go through a cooling phase which takes from 48 hours to 120 hours depending on the thickness of the castings. For example, our C200 plates are about 300 mm thick, so they have to cool down for at least 100 hours.
– Each casting has a process sheet which lists the related requirements, including cooling time.
Our main products are manganese crusher plates, including cone crusher liners and jaw crusher liners. In addition to other manganese steel parts, we also manufacture high chrome cast iron and other alloys.
For new items, the lead time is 45 days. For reoccurring orders, production can be completed in 30 days.
We keep our samples for 3 years.
We are certified for ISO9001:2008.
-We have two 4 meter vertical lathes that can machine castings up to 4 meters in diameter.
-For jaw crusher wear parts, we can handle parts in size up to 4 x 2.5 m (13 x 8 ft).
Government policies require us to have our
equipment tested once a year. Our own policy requires all equipment
to be tested twice a year, and some with quarterly calibration.
We use bottom pour ladle; the temperature is 1,420 degrees centigrade when pouring the
first product. Pouring temperature for the rest of the products from the same ladle is lower than 1,420
degrees centigrade.
We use two 5 ton induction furnaces and the maximum melt is 14
tons. We are planning to increase the melt capacity in the near future.
We are
able to produce 8,000 tons of castings a year at full capacity, and our
new plant, which is due to open in late 2020, would increase our
capacity to 15,000 tons annually.
