Products Description
With growing demands for Plastic Parts High Precision Industrial Fabrication in the industrial manufacturing industry, there has never been a greater need for high-precision manufacturing. Providing high-quality plastic products with strict tolerance requirements, which are so important in several applications, is by no means an easy task-it requires the latest technology, expertise, and attention to detail.
Applications of custom plastic parts in industrial manufacturing are endless. So many companies today rely on plastic parts to make specialized components to serve the purpose of productivity and efficiency in various manufacturing processes. This extends to the provision of custom parts whereby businesses can tailor their products to exact customer needs; hence, meeting their particular application requirement.
Industries that produce these custom parts use new manufacturing processes employing computer numerical control machining, injection molding, and other advanced technologies for high precision and quality standards. The new technologies will enable the creation of customized parts with high accuracy and reliability.
Injection molding provides one of the most effective ways of manufacturing parts with a high degree of precision. In this process, Plastic Parts High Precision Industrial Fabrications are melted and then injected into a mold under high pressure. This results in a highly accurate and repeatable product that can be made in large volumes.
CNC Machining: This is a subtractive process whereby a solid form is cut into desired shape. It is regarded as one of the most accurate means of developing plastic components that possess highly detailed features, since it can build complex forms with extreme accuracy. A technology that removes material from a block of plastic by means of a rotating cutting tool yields extremely precise parts.
There are a few advantages associated with the use of plastic elements in the course of industrial manufacturing processes. To begin with, these are lightweight and resilient materials, apt for application in extreme conditions, versatile, and easy to modify; hence, allowing the creation of components for special purposes to suit specific applications.
In a nutshell, Plastic Parts High Precision Industrial Fabrication play a vital role in industrial manufacturing to raise business productivity, efficiency, and performance related to specific applications. With advanced technology and manufacturing processes, high-quality plastic products are achievable to meet the high precision and performance standard requirements of many industries.
Process of Products
There are four steps:
- Pre-inspection:where the fabricated structural steel is viewed to ensure it has, if necessary, the proper venting and draining holes, bracing, and overall design characteristics necessary to yield a quality galvanized coating
- Cleaning: steel is immersed in a caustic solution to remove organic material such as grease and dirt, followed by dipping in an acid bath (hydrochloric or sulfuric) to remove mill scale and rust, and finally lowered into a bath of flux that promotes zinc & steel reaction and retards further oxidation of the steel… (steel will not react with zinc unless it is perfectly clean)
- Galvanizing: the clean steel is lowered into a kettle containing 850 F molten zinc where the steel and zinc metallurgically react to form three zinc-iron intermetallic layers and one pure zinc layer
- Final inspection: the newly galvanized steel is sight-inspected (if it looks good, it is), followed up by measurement of coating thickness with a magnetic thickness gauge

How does galvanizing protect steel from corrosion?
Zinc metal used in the galvanizing process provides an impervious barrier between the steel substrate and corrosive elements in the atmosphere. It does not allow moisture and corrosive chlorides and sulfides to attack the steel. Zinc is more importantly anodic to steel meaning it will corrode before the steel, until the zinc is entirely consumed.
How does the cost of hot-dip galvanizing compare to other corrosion protection systems, such as paints?
When compared with paint systems, hot-dip galvanizing after fabrication has comparable initial application costs and, almost always, lower life-cycle costs. In fact, the lower life-cycle costs of a hot-dip galvanized project make galvanizing the smart choice for today and tomorrow.
How long can I expect my galvanized steel project to last in service?
Hot-dip galvanized steel resists corrosion in numerous environments extremely well. It is not uncommon for galvanized steel to last more than 70 years under certain conditions. To get a good idea of how long your project will last, see the service-life chart.
Does the galvanized steel coating of zinc resist abrasion?
The three intermetallic layers that form during the galvanizing process are all harder than the substrate steel and have excellent abrasion resistance.
What causes wet storage stain and how can it be prevented?
Zinc on newly galvanized steel is very reactive and wants to form zinc oxide and zinc hydroxide corrosion products that eventually become the stable zinc carbonate. When galvanized steel is tightly stacked or stored in wet boxes that dont allow for free flowing air, the zinc forms excessive layers of zinc hydroxide, otherwise known as wet storage stain. Most wet storage stain can be easily removed with a cleaner or nylon brush. To prevent wet storage stain, store galvanized steel indoors or block it so that there is ample free flowing air between each galvanized article.
Why do galvanized steel appearances differ from project to project and galvanizer to galvanizer and is there any difference in the corrosion protection offered by the different appearing coatings?
The steel chemistry is the primary determinant of galvanized coating thickness and appearance. Continuously cast steel produced by the steel companies has a wide variety of chemistries, thus the different coating appearances.
There are several different additives that galvanizers may put in their zinc kettle to enhance the coating appearance by making it shiny, spangled or matte gray. The appearance of the coating (matte gray, shiny, spangled) does nothing to change the corrosion protection of the zinc coating.
Can galvanized steel in service withstand high temperatures for long periods of time?
Constant exposure to temperatures below 390F (200C) is a perfectly acceptable environment for hot-dip galvanized steel. Good performance can also be obtained when hot-dip galvanized steel is exposed to temperatures above 390F (200C) on an intermittent basis.
Why would you want to paint over galvanized steel?
Called duplex coatings, zinc and paint in combination (synergistic effect) produce a corrosion protection approximately 2X the sum of the corrosion protection that each alone would provide. Additionally, duplex coatings make for easy repainting, excellent safety marking systems, and good color-coding. Painting over galvanized steel that has been in service for many years also extends the life of the zinc coating.
