As a company specialized in manufacturing of drilling equipment and tools, Chang Shin International exports its products to more than 40 countries around the world. For potentially emerging overseas markets of this year, Chang Shin International decided to select its three flagship products – Waroc water hammer, CS power hammer, and CS power button bit- as its strategic players that can lead its overseas drive.
Waroc Water Hammer
Waroc, CSI’s water hammer, is operated by high-pressure water from a water pump instead of air compressors. So it can lead to dramatic savings on energy and other resources.
And Waroc water hammer is designed to protect the environment by using water from a recycling system. It also does not need lubrication oil for hammering, so there is nothing to worry about water & soil pollution because of oil sludge.
CS Power Hammer
CS power hammer is a mechanical hammer, operated by compressed air. The upper part is connected to a drill pipe from a rotary head of a drilling machine, and the lower part a bit. CS poser hammer is optimized to meet the demand for quick work in the processes of anchoring, quarry job, constructions and water well drilling. And these days, it is also being widely used in geothermal development field.
CS Power Button Bit
While the hammer hitting, button bit transmits energy directly to the rock base and accomplishes its function of cracking, CSI has accumulated expertise in designing and producing all kinds of button bits. Especially, Chang Shin International specializes in producing tungsten carbide bits for better cutting power and faster penetration speed.
Regarding such business areas, Chang Shin International is currently committed to all of the essential processes – designing every module needed for drilling works, producing, marketing, changing parts, consulting, and maintaining & repairing. This helped the company secure exclusive competitiveness in the drilling industry. Its current major business partners for hammers & bits are: ROCBIT in South Africa, PRE-MAT in Singapore, and BESTMA in the United States. The company’s total sales as of 2017 amounted to US$5 million, consisting of US$1.5 million in domestic markets and US$ 3.5 million in overseas markets.
One of its R&D projects is to develop further the state-ofthe- art drilling system as a new application of DTH drilling. Equipped with high technology and competitiveness in domestic and global markets, Chang Shin International takes pride in supplying top-quality drilling products.

First, it is a groundbreaking equipment in saving of the heating cost. You can save the heating cost by more than 60% ~ 70% compared with the gas, electric or oil boilers. Second, Heating Plant ELUS can be used semi-permanently while the existing industrial boilers have less than 10 years of useful life. Third, Heating Plant ELUS, manufactured in subminiature size, has a very high use of space. Fourth, Heating Plant ELUS is an eco-friendly product discharging no pollutants and the safest hot water providing equipment.
All of Wonjin Aluminum’s profiles have excellent costreduction effects in the production process due to the standardization of the designing, processing, assembling process. The aluminums profiles deliver excellent quality, precise extrusion. All manufactured products are wellrecognized among buyers who perceive it as a highly credible company having technologies accumulated over more than 30 years.
accordance with the usage. Home position setting is easy during the drilling process due to the V-line in the profile opening.
This mold has advantages of cutting costs, saving labor costs and significantly improving the stability of work due to the characteristic of high productivity. It also has effects of suppressing the half-finished product inventory, reducing the mold preparatory set-up time, and facilitating production management. Due to the high productivity, it has the advantages of labor-cost saving and mass-production in a short time. On the other hand, its disadvantages are that the dimensional tolerance becomes strict when manufacturing, designing is difficult, and there is a concern that noise may be generated.
As its characteristics, the entire process performed in one or more presses and the raw materials are automatically transferred using the feed bar. As interference with the mold can occur depending on the slide motion and the feed bar motion, there are many restrictions on the design and idle process is required.
PVC wrap from the company prevents moisture from food evaporation and keeps fish, vegetables, fruits and meats as fresh as possible with excellent oxygen permeability. In addition, its perfect sanitation management system helps automatic packing for your safe use.
stability and reliability are improved. High efficiency is maintained without a permanent magnet in the main rotor by optimization of a permanent magnet.
As the vacuum pump of this type uses oil for keeping lubrication and vacuum of the rotating part, a stable and reliable vacuum can be obtained, and thus this product can be applied to various industries.
The company is producing many kinds of saws including carpenter saws, folding saws, pruning saws, pruning saws for cutting fruit tree, and pipe saws.
