Last week, Weijing was able to deliver a set of unique 2-axis grinding machines to a Tunisian foundry and was very proud of it, because the 2-axis grinding machines were chosen for the round parts. To begin with, the technical director of the Tunisian foundry came to Weijing in January to order a grinding machine to remove residual material from round iron parts: Flywheel, disc brake, clutches. He found…

Last week, 2 new sets Weijin Degating Hammer started running at Shandong ConMet-Xin foundry. ConMet-Xin foundry is controlled by ConMet (US company) with 70% of shares, and ShangDong HaoXing Group with 30% shares. ConMet-Xin mainly produce components for heavy duty truck, such as wheel hubs, brake drums. It is not the first time for Weijing to provide pneumatic hammer to ConMet-Xin foundry. First 4 sets…

DAEHAN METAL MFG Co.,Ltd. decided for Weijing Auto pouring Please follow an interview we received from the Chinese supplier: What was the reason behind that they choose Weijing? The answer is quite simple: The Weijing Auto pouring machine doesn't need the foundry to dig the groundwork for the pouring machine and just needs at most 2 meters distance for machine to move horizontally. What does it mean to the…

Earlier foundry men used a robot fettling station for this application. Robot is quite limited when using many circular parts. A lot of technical expertise is required to program different sizes each time. A simpler machine, lower in cost and very versatile is Weijing two axis grinding machine which could be with two grinding stations needing only one operator to load and unload the part. This loading,…

Weijing produced its first degating hammer QC 65 set in June, 2013. It was the smallest one, providing 500 Joules of impact energy and able to degate a maximum neck size of around 90 mm. For Weijing's staff, it seems like it was just yesterday. Thanks to Weijing's strict quality control, its first foundry customer was happy with the hammer's performance. This resulted in a follow-up order for the Weijing…

Windmill castings are huge, so breaking the risers is an important step of the post-casting process. To break those large risers safely, efficiently, and at the lowest cost possible is one important duty of the part cleaning department. As one of the three largest foundries producing windmill castings in China, the Himile Foundry faced this problem 3 years ago - until they found Weijing Hammer at the M&M…

After the casting process, there are many casting runners left which we need to be broken into smaller pieces in preparation for the next melt, because smaller pieces save costs and space. The fettling shop becomes the starting point for the efficient and cost-effective loading of the furnace with the crushed scrap parts. There are still foundries which instruct their workers to hammer the runners away, but…

While the Weijing QC431 Hammer can provide 18000 Joules, giving it the power to knock off neck sizes of up to 250mm, when the neck size of the largest risers reaches 350-380mm, now-customer Tongyu Foundry had been using flame cutting to degate its castings, a much less efficient method. So the question arised - is there a hammer that could degate the largest risers in the world, with a neck size reaching…

Vertical molding lines can produce much higher volumes of castings than the horizontal, and these small castings should be degated in the shortest time. Degating efficiency, and inserting convenience/ease of use would be the key factors when an end user is choosing degating tools for a vertical molding line. And separating efficiency and inserting convenience are usually determined by the way wedge is…

Tongyu Heavy Industry, an important production base of MW-class wind power generator shafts and Wind Power Hub in China, approached Suzhou Weijing for its Degating Hammer after hearing positive reviews from Shandong Himile Machinery Co., ltd, also a main foundry of the biggest windmill castings in China. The Suzhou Weijing QC431 Degating Hammer can provide impact energy to 18000 Joules. This energy can…
