Heavy-Duty Powder-actuated Fastening Tool is designed for hard base concrete which is between C40 and C55.
A powder- Actuated Tool (often generically called a Hilti gun or a Ramset gun after their manufacturing companies) is a type of nail gun used in construction and manufacturing to join materials to hard substrates such as steel and concrete. Known as Direct Fastening , this technology relies on a controlled explosion created by a small chemical propellant charge, similar to the process that discharges a firearm.
Powder-actuated tools come in high-velocity and low-velocity types. In high-velocity tools, the propellant charge acts directly on the fastener in a process similar to a firearm. Low-velocity tools introduce a piston into the chamber. The propellant acts on the piston, which then drives the fastener into the substrate. (The piston is analogous to the bolt of a captive bolt pistol.) A tool is considered low velocity if the average test velocity of the fastener is not in excess of 100 m/s (330 ft/s) with no single test having a velocity of over 108 m/s (350 ft/s). High-velocity tools may not be made or sold in the United States[citation needed]; however, some made decades ago are still in use in the shipbuilding and steel industries. The main manufacturers of Powder Actuated Tools are Ramset, Hilti, Powers/DeWalt, Tomarco and Simpson Strong Tie.
Powder-actuated Fasteners are made of special heat-treated steel. Common nails are not used for powder-actuated fastenings. There are many specialized fasteners designed for specific applications in the construction and manufacturing industries.
Powder-actuated technology was developed for commercial use during the Second World War, when high-velocity fastening systems were used to temporarily repair damage to ships. In the case of hull breaches, these tools fastened steel plates over damaged areas.[1] These tools were developed by Mine Safety Appliances, for the United States Navy.[2] Powder-actuated tools were investigated and used prior to this development; they were used in submarine hunting during the First World War and were the subject of a 1921 United States patent (US Patent No. 1365869)

“External demand has become firm, and China’s strong demand has driven overall growth,†said Shimaru Yuji, the director of the Japan Machine Tool Industry Association. Japan’s overall order for machine tools in April increased by 34.7% year-on-year to 133.07 billion yen. The driving force behind the five-month growth year-on-year is China’s “buy buyâ€.
Beginning in February, China has seen a need for new models for Apple's smartphone "iPhone." In the Japanese factory automation equipment and robotic integrated manufacturer FANUC President and CEO (CEO) Inaba said that in addition to the demand for smartphones, "the demand for other fields such as automation equipment and robots is also very active." The Minister of Securities of Nomura Securities Research Department Saito Kishi also analyzed that "although growth has slowed down, it is still in good shape."
Japanese machine tool companies have enjoyed the benefits. Due to the recovery of Chinese demand, FANUC raised its performance forecast three times in FY2016 (as of March 2017). Although the assumed exchange rate is set at a higher level of 1 US dollar against 100 yen, it is expected that the fiscal year (as of March 2018) will still achieve double growth in revenue and operating profit.
In 2017, Yamazaki Mazak, a well-known Japanese machine tool company, will invest about 1 billion yen in two factories in China, increasing total production by 20%. Zhongxi Zhengchun, executive director of the company, said, "If this momentum is maintained, further enhancements will be considered."
The background to China's recovery in demand is that Chinese companies are accelerating investment in factory automation. The reason is that China's competitiveness as a manufacturing base has been in crisis in the context of rising labor costs. In response, the Chinese government introduced an industrial revitalization policy called "Made in China 2025" and supported the company.
However, Chinese demand has recently started to shine yellow. In terms of smartphones, data released by US research firm IDC on May 4th showed that China's smartphone shipments increased by only 0.8% from January to March 2017. China's smartphone demand accounts for about 30% of the global share. Although it has increased by about 9% in 2016, the current growth has stepped on the brakes.
The same is true for the automotive sector. According to data released by the China Association of Automobile Manufacturers on May 11, the sales of new cars in April decreased by 2.2% year-on-year. In addition to the January-February period affected by the Spring Festival holiday, sales have decreased year-on-year since August 2015.
Although China's new car sales performed well before March, it was driven by the government's small car tax cuts introduced in October 2015. The executives of a Japanese-owned car company warned that "the tax cut bubble may begin to burst."
In addition, there are concerns about China's overall macro economy. The reason is that the Chinese government has strictly restricted the flow of funds to overseas since the end of 2016, resulting in a large amount of domestic funds flowing to real estate. The expanding asset bubble may become an uneasy factor in ruining the willingness of Chinese companies to invest.
On the other hand, there has also been an argument in the Japanese machine tool industry to remain vigilant about the prospects. Although Japan’s precision machine tool maker Tsuji decided to increase production of high-performance small lathes, the company’s president, Nishijima, said that “there will be a warning to reduce the market and increase productionâ€. Japan’s large-scale machine tool company, Otsuka’s president, Ichiro, also warned that “the market in the first half of the year is definitely good, but it’s not clear in the second half of the yearâ€.
Is the grand occasion of the Chinese market actually demanding or pre-consumption of demand? The situation that has troubled Japanese machine tool industry companies seems to continue.
China’s strong demand for Japanese machine tools is hard to beat

Recently, "Nikkei Business News" reported that China's machine tool demand has remained firm. According to the April Order Quantity (determined value) data released by the Japan Machine Tool Industry Association, orders from China amounted to 31.1 billion yen (about RMB 1.912 billion), a year-on-year increase of 2.4 times. In the context of Chinese companies hoping to maintain the competitiveness of “world factoriesâ€, smartphones and auto factories have increased investment in promoting automation, which has driven the growth of orders in the Japanese machine tool industry.
