  zone heating
Most of the experiments were conducted in a two-zone heating furnace, wherein a copper-cuprous oxide mixture was heated in one zone and the copper-silica sample was heated in the other zone, all enclosed in a quartz capsule.
      
This information has allowed us to establish under which conditions single or multi-zone heating should be used in the OMVPE reactor.
      
A wafer temperature uniformity of better than 1°C was demonstrated for both an optimized single zone heating system under a selected combination of process parameters, and for a two-zone heating system over a wide range of the process parameters.
      
Modern technology abounds in extensive network wiring, security, and dual-zone heating/cooling systems.
      
The case should be provided with electric zone heating to maintain a melted lead temperature.

Quick change in the color or kinds of polymer materials often occurs in the hot runner injecting molding process. The time consuming and incomplete material change often affects the quality and productivity of products. In the practical production, multi injecting and using white material as the transition material are often used to achieve quick material change. Based on the rheological behavior of new and old plastic melt, the researches into these problems are carried out. The concept of drag material change process is presented, the physical model and mathematics model of the coflow process of new and old plastic melt in hot runner are built up, and the influence of the injection speed, the injection pressure, the viscosity difference and the temperature on drag material change process are analyzed systematically. Using multi point heating and temperature controlling, and monitoring the viscosity difference of the new and old plastic melt, the ability for material change in the late process can be improved greatly, which can solve the process problems, i.e. it is easy first and then difficult, quick first and then slow for the change of materials, and improve the ability for material change in the whole material change process.
