Punching oil is an industrial lubricant used for punching holes or forming shapes in metal. It is generally classified as a metal forming lubricant and is also known as punching oil. Applications Punching oil is widely used in the manufacturing processes of motor cores, heat exchangers for air conditioners and refrigerators, radiators for automobiles and…

Industrial lubricant market is already saturated with numerous manufacturers. However, punching oil, unlike general-purpose industrial lubricants, is mainly used by large-scale manufacturers and requires strict testing and qualification before being adopted into mass production processes. In particular, major corporations often demand formal approval processes and documentation, making entry into this market quite difficult. Due to…

When we think of metalworking industries, we often picture massive machines roaring as they cut, bend, and stamp red-hot metal. In all these intense processes, there’s a hidden but crucial player—punching oil (also known as stamping or press oil). At Dyna, we pride ourselves on our unmatched expertise in the field of punching oil. Our…

In recent years, sales of electric vehicles (EVs) have been increasing rapidly and are expected to grow even more steeply in the coming years. As a result, global automakers are announcing the discontinuation of internal combustion engine (ICE) vehicle production. This shift has prompted companies previously involved in ICE vehicle manufacturing to quickly pivot toward…

What is a Radiator? A radiator is a cooling device installed in front of a car engine. Its primary role is to dissipate the heat generated within the vehicle. The engine, often referred to as the heart of the car, continuously receives fuel and generates intense heat during combustion. If this heat is left unmanaged,…

Motor Cores The demand for motors is exploding due to the rise of electric vehicles. This trend is expected to continue long-term, and the stock prices of related companies are also steadily increasing. Not only electric vehicles, but also many products around us use motors.Motors are essential components in almost all household appliances such as…

There are various types of synthetic coolants supplied domestically, but their cooling performance and pros and cons vary greatly depending on their physical and chemical properties. Therefore, appropriate selection criteria are essential. Among these, PVA and PEG have largely been discontinued both domestically and internationally due to environmental concerns related to their thermal decomposition byproducts.…

(1) Thermo-Mechanical Treatment Thermo-mechanical treatment refers to a method that combines plastic working and heat treatment. This method is used to obtain microstructures and mechanical properties that cannot be achieved through conventional heat treatment or plastic working alone. Typically, hot working is performed in the relatively high-temperature austenite region. However, to improve the strength and…

Water-soluble quenching fluids are primarily composed of polyalkylene glycol (commonly referred to as PAG, or polyoxyethylene oxypropylene glycol), which is a non-flammable aqueous solution with a small amount of corrosion inhibitors added. PAG is fully soluble in water at temperatures below approximately 74–88°C, but separates from water at higher temperatures. When a pre-heated metal part…
