Advantages of Automatic Vacuum Emulsify Mixer

It is apparent that automatic vacuum emulsify mixer used to manufacture the high viscosity products, especially for cream and ointment, often encounter the problem of air bubbles occurring in products during agitation due to oxidation processes, which lessen the quality of products. The automatic vacuum emulsify mixer equipment can eliminate this problem and increase the smoothness and fineness of products. 

The combination of special designed high speed emulsifying head and low speed blade agitator with attached scrapers allows to achieve a high efficiency of mixing & homogenizing process. The mixture is sucked through the narrow gap between the high speed rotating rotor and fixed stator of emulsifying head. Due to the turbine effect of emulsifying head, the circulation of product in the mixing vessel is formed.


Brief Introduction of Galvanizing Process

There are several steps for galvanizing process in galvanizing equipment. Below are basically four steps for you to follow.

 

Step 1: Preparation

As the steel products arrive at our plant, they are inspected for drainage and venting requirements. In the staging area, an efficient handling method is chosen to transport the material through the initial cleaning process.

 

Step 2: Cleaning

The material is cleaned in three steps:

Total immersion in a hot alkali solution to remove organic compounds

Acid pickling removes rust or scale

Fluxing eliminates oxides from the surface of the steel and promotes the proper metallurgical bonding of the zinc in the next step.

 

Step 3: Hot Dip Galvanizing

The steel is totally submerged in a bath of molten zinc until it reaches bath temperature (approximately 840° F, 449° C) at which time zinc reacts with the steel to form zinc/iron intermetalic layers on all surfaces, inside and out.

 

Step 4: Quality Inspection

The galvanized steel product is cleaned, weighed and then thoroughly inspected for coating thickness, appearance and compliance with applicable ASTM specifications. Calibrated instrumentation insures efficient inspection.

An Overview of Injection Molding

Injection molding is a fast, automated, versatile process that can produce precise, complex three–dimensional parts from a fraction of a gram to more than a hundred kilograms, in virtually any plastic material. The process starts with feeding small plastic beads into a heated screw and barrel system that melts the plastic into a high–viscosity liquid. The screw then forces the molten plastic into a closed mold that provides the shape, cooling and solidification, and finally ejects the part.

Injection molding is fast and can be economical. But because every part needs its own costly injection molding tool, the process is economically viable only for mass production, usually more than 10,000 parts. Injection molding tools take weeks or months to build. Often, design mistakes become apparent, requiring time–consuming mold corrections. Multiple iterations may go from the producer to the tool builder until the final part design and quality are achieved, increasing costs and product time to market.


The Process of Plastic Injection Molding

The Process and Equipment

Because most engineering thermoplastic parts are fabricated by injection molding, it is important for the designer to understand the molding process, its capabilities and its limitations. The basic process is very simple. Thermoplastic supplied in pellet form are dried when necessary, melted, injected into a mold under pressure and allowed to cool. The mold is then opened, the parts removed, the mold closed and the cycle is repeated.

 

The Molding Machine

Melting the plastic and injecting it into the mold are the functions of the plastifying and injection system. The rate of injection and the pressure achieved in the mold are controlled by the machine hydraulic system. 

 

The Mold

Mold design is critical to the quality and economics of the injection molded part. Part appearance, strength, toughness, size, shape, and cost are all dependent on the quality of the mold. Key considerations for Engineering Thermoplastics are:

-Proper design for strength to withstand the high pressure involved.

-Correct materials of construction, especially when reinforced resins are used.

-Properly designed flow paths to convey the resin to the correct location in the part.

-Proper venting of air ahead of the resin entering the mold.

-Carefully designed heat transfer to control the cooling and solidification of the moldings.

-Easy and uniform ejection of the molded parts.

When designing the part, consideration should be given to the effect of gate location and thickness variations upon flow, shrinkage, warpage, cooling, venting, etc. Your DuPont representative will be glad to assist with processing information or mold design suggestions. The overall molding cycle can be as short as two seconds or as long as several minutes, with one part to several dozen ejected each time the mold opens. The cycle time can be limited by the heat transfer capabilities of the mold, except when machine dry cycle or plastifying capabilities are limiting.

 


Buy a heating pad for Japan's Tsunami Survivors

(Kairo heating pads being distributed.)
 
Thousands of people who survived the tsunami on March 11, 2011 still live in temporary housing units in the Northeast Tohoku region. The temporary houses are small box-like trailers with some families living in 300-square-feet of space. This year’s severe winter weather has prompted Japanese nonprofit Project Fumbaro to fundraise for disposable heating pads to help these residents who may not have suitable heating in their housing units. This fundraiser is not only meant to keep people warm, but also to continue to give them hope.
 
(Temporary houses covered in snow this winter.)

Jonie Quimino and Christine Hitt visited the Tohoku region in September 2012 and met with Fumbaro Kyoto chapter representative Chiyoka Ajimoto (pictured left, below) on-site in Minamisanriku, an area that was completely wiped out by the tsunami. Ajimoto works directly with the people of Minamisanriku to help them understand they have not been forgotten. When Quimino and Hitt visited, Ajimoto had just completed a fundraiser to help the fishermen in the town. Donations were used to supply the fishermen with new buoys and fishing net weights. What many people do not realize is that while the earthquake and tsunami occurred two years ago, many survivors are still coming to terms with their losses and continue to need support in many areas. “Not being forgotten” is what countless people and survivors conveyed repeatedly, says Quimino and Hitt.

Witnessing firsthand the impact that these donations had, Quimino and Hitt decided to help with Project Fumbaro’s efforts, along with other people from Honolulu, by extending aloha from outside of Japan.
 
 
Project Fumbaro’s goal is to raise enough money to give heating pads to as many people as possible in the tsunami-devastated regions to last them until spring, which is the end of April. One disposable, and wearable, heating pad costs approximately $11 and each has a lifespan of 16 hours. With your donation, you’ll not only be helping someone directly and personally affected by the tsunami get warm, but you’ll also be giving people hope and letting them know that they are not forgotten.

Molding Process

Injection molding utilizes a ram or screw-type plunger to force molten plastic material into a mold cavity; this solidifies into a shape that has conformed to the contour of the mold. It is most commonly used to process both thermoplastic and thermosetting polymers, with the former being considerably more prolific in terms of annual material volumes processed. Thermoplastics are prevalent due to characteristics which make them highly suitable for injection molding, such as the ease with which they may be recycled, their versatility allowing them to be used in a wide variety of applications, and their ability to soften and flow upon heating. Thermoplastics also have an element of safety over thermosets; if a thermosetting polymer is not ejected from the injection barrel in a timely manner, chemical crosslinking may occur causing the screw and check valves to seize and potentially damaging the injection molding machine.

Injection molding consists of high pressure injection of the raw material into a mold which shapes the polymer into the desired shape. Molds can be of a single cavity or multiple cavities. In multiple cavity molds, each cavity can be identical and form the same parts or can be unique and form multiple different geometries during a single cycle. Molds are generally made from tool steels, but stainless steels and aluminum molds are suitable for certain applications. Aluminum molds typically are ill-suited for high volume production or parts with narrow dimensional tolerances, as they have inferior mechanical properties and are more prone to wear, damage, and deformation during the injection and clamping cycles; but are cost effective in low volume applications as mold fabrication costs and time are considerably reduced. Many steel molds are designed to process well over a million parts during their lifetime and can cost hundreds of thousands of dollars to fabricate.


Injection Mold

Material is introduced into the injection molding machine via a Hopper.  The injection moulding machine consists of a heated barrel equipped with a reciprocating screw (driven by a hydraulic or electric motor), which feeds the molten polymer into a temperature controlled split mould via a channel system of gates and runners. 

The screw melts (plasticises) the polymer, and also acts as a ram during the injection phase. The screw action also provides additional heating by virtue of the shearing action on the polymer.

The polymer is injected into a mould tool that defines the shape of the moulded part. 

The pressure of injection is high, dependant on the material being processed; it can be up to one thousand atmospheres.  Tools tend to be manufactured from steels, (which can be hardened and plated), and Aluminium alloys for increased cutting and hand polishing speeds.  The costs associated with tool manufacture means that injection moulding tends to lend itself to high volume manufacture.  Details of process costing can be found at:

The tool can be used to manufacture one consistent part in a repeating process or incorporate multi cavities (a multi impression tool), that is many components can be manufactured on the same tool repeatedly with a single injection. 

It should be noted that, whilst in the animation the flute pitch of the screw is shown as constant along its length, in practice it varies considerably dependent upon the polymer being processed. In particular the root diameter increases from hopper to nozzle to provide compression to the melt.

Injection Molding

Injection Molding (or Moulding to use the UK spelling), along with extrusion ranks as one of the prime processes for producing plastics articles. It is a fast process and is used to produce large numbers of identical items from high precision engineering components to disposable consumer goods. 

 

Injection mouldings count for a significant proportion of all plastics products from micro parts to large components such as bumpers and wheelie bins.  Virtually all sectors of manufacturing use injection moulded parts - the flexibility in size and and shape possible through use of this process have consistently extended the boundaries of design in plastics and enabled significant replacement of traditional materials thanks to light weighting and design freedom.  The table below shows the type of products that can be injection moulded, but is by no means comprehensive.
