Abstract

PURPOSE: Provided is a development tank in an automated film developer wherein a sheet is used as raw materials with showing certain thickness so that it contributes to reduce the weight of the development tank remarkably. CONSTITUTION: The development tank in the automated film developer is characterized by using a thick board to produce a formation product with certain thickness, excellent appearance and light weight excluding unnecessary materials through vacuum formation. Also in formation, transformation is perfectly excluded to produce an exact formation product.

Description

Developing tank for automatic film development {VACUUM FOR MAIN TANK (VFMT-01)}

In the X-ray film developing machine for medical devices, development tanks are generally used for film development. In general, special chemicals are used to use "SUS" or "resin" injection. SUS requires many processes such as processing, welding, and pressing. After assembly, the tolerances are severely generated and many defects are generated.In the process of use after assembly, it is the cause of defects due to welding and assembly failures. Although it is intended to produce, the injection mold cost is expensive, so it is difficult and heavy, and it is difficult to produce due to excessive cost in small quantity production.

The present invention is easy to UP GRADE REVISION due to the low price and low price by producing a special vacuum molding mold molding method. It does not take long injection time like mold injection molding, so it is possible to produce small quantities of various kinds required in film developing. In addition, since the raw material is made of SHEET, it is generally easy to purchase, and the thickness is kept constant using vacuum plate rather than mold injection molding, and the thickness is kept constant. Can be. The development tank manufactured by the conventional injection is a mold injection molding injected by a molding injection molding machine, and the size of the tank is large, so there is a problem in deformation and warping unmolding.However, the VFMT-01, which is injected by vacuum, is light in weight. And cost effective inventory management.

3 is a perspective view of a developing tank of the present invention

Conventional SUS type developing tank is difficult to assemble due to heavy welding and weight, as shown in Figure 1, leak and tank size tolerance is too high, and the cost is too high, mass production is impossible. In addition, welding causes cold soldering (A), resulting in low aesthetic value. The developing tank of the second degree injection type has a high thickness consumption due to inconsistent thickness control. As a result, the weight becomes heavy and a lot of deformation due to shrinkage and expansion in the thick portion becomes a cause of failure. As the space is formed as B, the thin part is not subjected to the force, and the deformation may easily come in or out. In order to solve this conventional problem, the developing tank of the third degree vacuum type is vacuum molded, and the thickness is constant, and the thickness is constant as in C, and the weight is light, because it is not as colorful as the injection molding of the exterior and unnecessary raw materials are not filled. This results in a lighter weight of the raw material and a smaller SIZE, which results in almost no deformation during molding, resulting in accurate molding.

It is manufactured by special vacuum molding, which can significantly reduce the cost of raw materials, and it does not take long injection time, so it is possible to produce small quantities of various kinds, so that it is not necessary to produce unnecessarily. By using a regular plate, a certain thickness can be maintained and the development tank weight can be significantly reduced. Unlike mold injection molding, which causes deformation and warping unmolding due to size and thickness, it is possible to form a light and accurate molding.

Claims (3)

When converting from mold injection molding to vacuum molding, the mold cost can be greatly reduced, and the UP GRADE REVISION can be easily done with low price, making it suitable for small quantity production. As the time required for injection is not long, it can drastically reduce molding cost. When molding by conventional mold injection molding, problems related to deformation and non-molding due to the appearance size and thickness of the tank, etc. are injected by vacuum molding, and the thickness and appearance are kept constant by using a certain sheet. none.
