Basic Technology

Injection molding technology involves the injection of molten plastic into one or several cavities via a hot-runner system (melt-channel distribution system) and rapid cooling of a preform to a low temperature. At this point the freshly manufactured article can be ejected from the cavity. In multilayer technology, more than one plastic resin is injected into the cavity. [Pg.18]

The different resins are molten in separate injection units, conveyed in separate hot-runner channels, under pressure and high temperature, to an injection nozzle, which is the gate area for the molten plastic, into the cavity. [Pg.18]

For the process, a machine used had one injection unit for virgin PET and another injection unit for reground PET flakes. The individual steps of the process are described below. [Pg.18]

The process of TBV production can be divided into four main steps as shown in Fig. 4.2 (i) cooking of grape juice (ii) cooked must fermentation (iii) acetic oxidation and (iv) slow aging of vinegar. The cooking of the grape juice takes between 12 and 24 h and produces chemical and physical [Pg.148]

Cooking is presumed to exert a key role in the TBV quality. The transfer of mass and energy takes place, and many chemical reactions and physical transformations are activated. Cooking induces the formation of compounds that will act as precursors in the formation of particular sensory-related constituents of TBV at the same time, it induces the formation of compounds potentially toxic for microbial activity and/or human consumption. [Pg.151]

FIGURE 4.3 Schematic representation of process streams during must cooking (upper side). Symbols indicate the steady-state condition (bottom side) L, (kg/batch) is the fresh grape must entering the open pan G2 (kg/batch) is the water vapor leaving the open pan G, and H2 (kg/batch) are the hot-dried air streams w, (kg/kg) is the solid concentration in L, T is temperature (°C). [Pg.152]

Therefore, the amount of water lost by vaporization at boiling temperature per batch can be calculated by [Pg.152]


There ate three basic technology options for making solar cells with do2ens of variations on each. These approaches ate conveniently grouped as follows thick (- 300 fiTo) crystalline materials, concentrator cells, and thin (- 1 fiva) semiconductor films. [Pg.470]

While all these paramclcrs are extremely essential for a process line, with the R D in the field these limitations have been overcome with the use of phasor controls. To implement the.se controls different manufacturers have tidopled different control and feedback systems to monitor and control the torque and field components. They have also given these controls different trade names. The basic technological concept remains the same but process implementation may vary from one manufacturer to another. Below we attempt to identify the more common phasor controls introduced by a few leading manufacturers. [Pg.104]

These reactors all work on very similar principles and will be discussed based on the example of the Berty reactor, of which more than 500 are in operation around the world. The Berty reactor shown in Figure 2.4.3 a has much empty volume and is laborious to open and close. Another version of the Berty reactor (made by Basic Technology, Inc.) is shown in Figure 2.4.3 b. This 2-inch model was developed for quick exploratory studies on small samples of catalysts. The maximum catalyst sample volume is 15... [Pg.50]

If a manufacturer has modified their own device they can avail of a special 510(k) procedure for declaring substantial equivalence to their existing device, provided that the intended use or the basic technology has not changed. They must apply design controls and risk analysis to the development process, but the advantage is that they can receive a faster review process. [Pg.203]

In this study, we developed microchannel PrOx reactor to control CO outlet concentrations less than 10 ppm from methanol steam reformer for PEMFC applications. The reactor was developed based on our previous studies on methanol steam reformer [5] and the basic technologies on microchaimel reactor including design of microchaimel plate, fabrication process and catalyst coating method were applied to the present PrOx reactor. The fabricated PrOx reactor was tested and evaluated on its CO removal performance. [Pg.654]

The basic technology for the preparation of sample material is similar in all TLC preparations, irrespective of the origin of the hpid and specific preparation method for a variety of biological samples [43]. The most important factor is the solubihty of the sample. The lipid sample must be completely soluble in the dissolving solvent prior to the application and must be free from water. Either toluene or chloroform is commonly used as the solvent to dissolve hpid materials. The dissolving solvent should be nonpolar in namre and volatile at such a concentration that the hpid components in the sample are completely adsorbed throughout the entire thickness of the layer as quickly as possible. Although sample sizes as small as 1 to 10 pi can... [Pg.306]

Olefins plants, for the most part, all have the same basic technology, but the process flows differ with the varied feedstocks that can be used. This chapter will cover in some depth the feeds, the hardware, the reactions, and the variables that can be manipulated to change the amount and mix of products. The physical properties of ethylene and propylene, which present some unique handling problems, will be covered also. [Pg.65]
