ACROSS Manufacturing Technology
Conventional Method

ACROSS PY Method

Conventionally, C/C composite used to be expensive and time consuming to manufacture due to its complicated processing method such as CVD (chemical vapor deposition) and CVI (chemical vapor infiltration). We have simplified the manufacturing process by using a new patented method called PY (preformed carbon fiber yarn), resulting in great reduction in time and cost.

By controlling the directional arrangement and the length of carbon fiber reinforcement that supports the carbon matrix, we are able to change the characteristics of the C/C composite so that it can be used for different kinds of application.
ACROSS Carbon/Carbon/Metal Composite Technology

We offer variety of C/CMC composites with special characteristics to suit different kinds of application. By controlling the pores of carbon matrix structure, we are able to put in different kinds of metal and create custom composite.
Heat Treatment
Fixture systems undergo tremendous heat load during heat treatment processes. Fixtures and grids made from conventional steel last only several months before repair is needed. ACROSS C/C composites fixtures and components are ideal for this application often lasting more than 5 years and absolutely maintenance free. The cost benefits are enormous when weight reduction and parts processed are accounted for.

Semiconductor
Material requirements for components such as crucibles and screws used during crystal cultivation processes require extreme purity levels and other characteristics. ACROSS C/C components and parts will meet and exceed these extreme conditions required which cannot be attained from ultra-pure graphite or conventional C/C elements.

Photovoltaic
As the world demand for alternative energy sources increases, the need for Photovoltaic manufacturers to produce more efficient equipments will rise. To keep with this trend ACROSS can provide with high standard C/C parts including plates and fasteners that can withstand the conditions and pace of modern solar equipment manufacturing. Not only do we provide the quality parts and services but will also support through fast delivery for the volume you require.

Automotive
In addition to the custom jigs and fixture components used for heat treating of automotive parts, ACROSS also produces high performance automotive components including racing clutches, brakes and LSDs. By utilizing ACROSS Carbon/Carbon technology, we can assist you in boosting your performance whether your needs are for high performance vehicles or energy efficient automotive supplies.

Aerospace
As the payload on aircraft systems gets larger, the performance of parts and components will also need improvements to keep in line with this movement. C/C demand will grow as well. Aircraft brake is one application which ACROSS Carbon/Carbon technology can take advantage of. The excellent strength-to-weight ratio makes them optimal for these applications.

Liquid Crystals Manufacturing
In growing support of LC industry, ACROSS C/C parts such as robotic arm tools exhibit outstanding performance when utilized during the transport of glass substrates. The growing demand for larger glass substrates and lightweight robotic grippers makes ACROSS composites an excellent substitute for conventional ceramic materials. The significant characteristics as relevant to the LC industry are its lightweight structure, excellent strength and high heat resistance.

Railway
ACROSS C/C composites are being used widely as sliding boards to collect electrical power in rail systems. It keeps the electrical resistance low by compounding the C/C with copper alloy. It has very high rigidity, good resistance to wear, high arc-resistance, and less damage to power lines in comparison with metal boards.

Other Industries
ACROSS C/C composites are vital in various other industries. Glass processing requires material with excellent thermal shock resistance as well as heat resistance. Hard metal tool manufacturers require robust furnace supplies including sintering trays. ACROSS C/C is the optimal material for these demanding processes.


Carbon/Carbon Composites
One of the most advanced and promising engineering material is the carbon fiber-reinfor ced carbon-matrix composite (C/C composites). Compared to other materials such as graphite, ceramics, metal, and plastic, it is light and strong and can withstand temperatures over 2000℃ without any loss in performance.
