OK-
Let me try this again.
I didn\'t mention the full belley project when I released it (Peanut Sheller)
But obviously, people are very interested in plastic molds.
There are several different varieties of injection molding, but it can basically be described as forcing the liquid plastic into the metal mold under high pressure.
Most of the injection molding is done with high temperature molten plastic and then quickly cooled inside the mold.
Take the part out of the mold and repeat the process.
The benefit of this technology is that it can make thousands or millions of components very quickly and cheaply.
The disadvantage of this technology is that molds are usually expensive. (
There are many variables here.
Mold design life, cycle time, etc)
Usually you make thousands of parts with this technology.
This makes the cost of the mold very small on the basis of each part.
There is also a technology called RIM (
Reaction Injection molding).
These molds cost less than other molds, during which the cooled liquid plastic is injected into the mold and chemically installed in the mold. (
Like epoxy or fiberglass, only polymer plastic)
To start with any of these paths, you need to start with a product that takes shape into consideration during production.
There are many product details that may make the parts easy to form or difficult to form.
If you have a basic product concept or design then you need someone to develop it into a complete 3D CAD model.
I have attached an example of a CAD model for you to view.
In addition to this, depending on the size and nature of the product, the cost and direction you should take will be significantly different.
Dwayne EsterlineGI Engineering Co. , Ltd. >>>>>Hi-
I am going through previous reviews and I think I will give me 2 cents.
If there is a real interest or demand for a large number of molds, I can help develop injection molds and plastic versions that produce fiberglass molds.
There are a wide variety of high-strength polymers to choose from, but I bet we can make the mold for less than $10 per unit.
We will be able to produce them in hundreds, thousands or tens of thousands.
It\'s cheaper to have more quantity.
In contrast, think about the 5 gallon plastic bucket and plastic lawn chairs available.
The manufacturing process is the same and the equipment is easy to buy where I live. Any thoghts?
The first step in injection molding is to develop a 3D CAD model of the product. (Computer model)
In the process, the designer will take your concept, sketch, or prototype, evaluate its prototyping, and then draw it in a computer environment. Why?
In modern mold manufacturing, all machines and equipment are driven by computers.
Your design can be evaluated by computer, and the mold will be cut through the machining center operated by the computer.
Through this process, experienced designers will advise you on changes that may be needed to make the molding process as cheap as possible.
A good CAD designer can work from your sketches, drawings and even rough prototypes.
Many companies can offer this service. (
Do an Internet search for product designers)
I have been designing tools, equipment and manufacturing processes for many years.
I use SolidWorks and AutoCAD design software.
You can learn more about our company on our website. Giengeringco.
The next step is to choose the most economical manufacturing process.
Each manufacturing process has advantages and disadvantages.
The goal is to find the right balance between precision, production speed and cost.
To put it simply, the production is faster and the accuracy is higher, usually equal to the higher cost. (
As a general rule)
To choose the process that best suits your project, you need to set some clear goals.
Answer the following questions: 1.
How many parts do I have to make?
10, 1,000, 10,000, 100,000 etc2.
What productivity do I need? (
How many parts per week, da, hour, year, etc)3.
What materials do I need to make? (
What plastic?
You may need help from a professional)4.
What is the target cost for each of my components? 5.
How accurate is the part tolerance? 6.
How big is the component? 7.
What are the features of this part? (
Holes, snapshots, thin ribs, textures? ? )
After you have answered the above questions, these answers will help guide you in choosing the manufacturing process.
For this note, let\'s assume that you want to make a simple part that is about 4 inch square meters.
This part is a consumer product made of ABS plastic, we want it to cost less than $10 per piece, we want to produce $1,000 per year, we expect to produce a total of 10,000 parts.
