What is titanium plate?
Titanium sheet is a metal material with excellent corrosion resistance and high strength, often used in aerospace, medical devices, automotive and chemicals. Due to its lightweight, toughness and ease of processing, titanium sheet is favored in more and more fields.
Why do I need titanium sheet perforation?
There are many applications where titanium sheets need to be perforated. For example, holes are made for medical instruments to allow drugs, gases or liquids to enter or exit the body. In the aerospace field, titanium plate holes are used to reduce the weight of the aircraft, improve the speed and maneuverability of the aircraft; at the same time, the location, size and number of holes also affect the aerodynamic performance of the aircraft. In industrial equipment processing, titanium plate holes are used for screw fixing, bracket installation and wire routing, as well as equipment in addition to corrosion and heat dissipation and so on.
Titanium plate drilling method
With the progress of technology, titanium plate drilling method is also increasingly diverse, generally divided into chemical (electrolytic) drilling method, laser drilling method, mechanical drilling method and EDM drilling method.
Chemical (electrolytic) perforation method
Chemical perforation method utilizes a specific etchant to accelerate the corrosion of the uncovered areas and the holes obtained. The chemical etching method can be used to obtain the size and shape of the desired hole under controlled pressure, temperature and time. This method is highly accurate and can produce porous, elongated, curved and complex titanium sheet prototypes. However, the chemical perforation method is more polluting to the environment and requires stringent handling and wastewater treatment.
Laser perforation method
Laser perforation method uses a laser beam to cut or melt the desired part, and the perforated titanium sheet is obtained by the titanium sheet absorbing the laser beam and generating heat, which melts or vaporizes the surface. This method of production is the most accurate, and can achieve precision down to a few micrometers. Also, this method allows for breakable holes, small diameter holes and high quality holes. The disadvantage is that the equipment is expensive and requires a high level of technical staff to operate.
Mechanical drilling method
The mechanical drilling method uses conventional CAD design drawings and CAM programs used to create the holes. By combining titanium plates using different sizes and shapes of drill bits, holes can be created to meet the requirements. Mechanical drilling is a method of manufacturing titanium sheets that distributes power evenly, does not require unnecessary treatment of the environment, allows single holes to be used in multiple batches, and is less costly than laser drilling. However, the problem faced by most mechanical drilling methods is the difficulty in achieving the required accuracy.
Electro-discharge drilling
Electro-discharge drilling involves forming holes by discharging a pulsed high-voltage electric current between a conductive plate and an electrode in an electric field environment. The disadvantage is that when a large number of holes are processed, the investment and invoicing costs are much higher than those of chemical etching and mechanical drilling methods.
Summary
Titanium plates have a wide range of uses in manufacturing, medical devices and aerospace. Perforation for titanium plates is a common need and there are several main methods such as chemical, laser, mechanical and EDM. Each method has its own unique advantages and drawbacks, and the appropriate method needs to be selected based on actual needs and budget.
