摘要： PURPOSE: A method and an apparatus for fabricating a clad pipe for plastic optical fiber, a clad pipe fabricated thereby, and a plastic optical fiber fabricated by a clad pipe are provided to enhance the productivity by restraining unevenness on an inner surface of the clad pipe and increasing an extruding speed. CONSTITUTION: A method for fabricating a clad pipe for plastic optical fiber includes a process for cooling an inner surface of the clad pipe(27) in an extruding process by a melting extruding machine before an extruded resin is crystallized at a temperature less than a melting point of the extruded resin. The extruded resin is formed with a fluorine resin. The fluorine resin includes at least polyvinylidene fluoride. In the process for cooling an inner surface of the clad pipe in an extruding process, gas or liquid are injected into the inner surface of the clad pipe.

摘要： Provided are a flow casting die, a die head manufacturing method and a film manufacturing method capable of suppressing the generation of cracks when a DLC film is formed on a base of a die head. A flow casting die is equipped with a die head (82) that is coupled and detached to and from an outlet of a dope. The die head (82) has a base (85), an underlayer (9.2) and a DLC film (86). The base is constituted of stainless steel, and the underlayer (92) is constituted of tungsten carbide (WC). The DLC film is formed on the underlayer (92). A combination of a linear expansion coefficient, a length (LY) of a longitudinal direction of the die head (82) and a heating temperature in a vapor phase forming method is determined such that stress applied on the underlayer (92), which is calculated from external force due to heat expansion deformation of the base (85) and the underlayer (92), wherein the stress is less than rupture stress. The underlayer (92) and the DLC film (86) are formed on the basis of this combination.
摘要翻译：本发明提供一种在模头的基底上形成DLC膜时可以抑制裂纹产生的流铸模，模头制造方法和膜制造方法。流铸模具配备有模头（82），模头（82）与涂料的出口连接和分离。模头（82）具有底座（85），底层（9.2）和DLC薄膜（86）。底座由不锈钢构成，底层（92）由碳化钨（WC）构成。 DLC膜形成在底层（92）上。确定线膨胀系数，模头（82）的长度方向的长度（LY）和气相形成方法中的加热温度的组合，使得施加在底层（92）上的应力被计算由于基部（85）和下层（92）的热膨胀变形而产生的外力，其中应力小于断裂应力。基于该组合形成底层（92）和DLC膜（86）。

摘要： PURPOSE: A flexible die, and a method for manufacturing a die head and a film are provided to form a DLC film with a long lifetime on the die head and to prevent the die head from bending. CONSTITUTION: A flexible die(21) comprises a pair of side plates(71), a pair of rib plates(72), and a DLC membrane. The pair of side plates is separated facing each other. The pair of rib plates is installed from one side of the side plate to the other side of the side plate. The pair of rib plates faces each other. The DLC membrane is installed on an end part of a die head. The DLC membrane is formed at the treatment temperature of 130°C~ 200°C.
