Plastic Injection Molded Parts design for Many Modern Industries

Plastic part design is important for many modern 
industries today. Today’s heavily technological society has made some aspects of  plastic part design more challenging in certain respects.
For one thing, the market changes very rapidly in a highly technological society like this one. This means that goods of all kinds need to be produced quickly and channeled into the marketplace rapidly. As such, the professionals involved with the design stage of all products will have to work even more efficiently and quickly. While speed and efficiency have always been valued in the world of manufacturing, the market changes quickly enough these days that many of these traits are even more important now.
The modern world of information technology has obviously increased the demand for many plastic parts as well. When people look at their laptops, smartphones, and other devices, they should consider the amount of plastic that went into making them in the first place. A typical smartphone handset will be made from a wide range of materials, but about 40% of it will be plastic.
It’s true that in a heavily technological society, the market moves quickly in general. However, this effect is particularly pronounced with regards to smartphones and similar devices. People will want to upgrade their devices very frequently these days. There’s a lot of pressure on most companies to produce new and advanced devices constantly.
This means that designers and other people involved in the manufacturing process will have to work quickly and constantly come up with new and creative ideas. The design of the individual plastic parts that people will encounter when looking at their devices will also vary, even if those plastic parts look relatively similar.
The fact that the specific plastic parts will only partly vary from one device to another actually makes the design process more difficult in some ways.
Making these parts both unique and effective requires very careful engineering.
The aesthetics of many modern plastic parts will also be important. People spend so much time handling their devices that they absolutely want them to look nice. They want devices that are made with smooth plastic parts that will be easy to handle for long periods of time during the day.
However, people seem to have the same standards for plastic parts all throughout many modern industries. When people compare modern plastic products with historical plastic products, it seems that many of the modern versions really have been created with a particularly high degree of care.
The tools used in plastic injection molding have certainly improved over the course of the last several decades. As such, it’s actually possible to create much more intricate and appealing designs in the modern world.
Modern plastic injection molding firms will have access to these modern tools, and they can use them to create excellent plastic parts that were designed according to a very exacting set of standards. Plastic parts are used everywhere today. It’s essential to work with plastic injection molding firms in order to receive a high-quality plastic part design since all of these trends won’t change any time soon.

What are some advantages of using plastic over metals?

Going back as far as the 50s, plastic part manufacturing has become increasingly common. It has even, in some cases, exceeded metal manufacturing. However,
even now, over half a century later, many manufacturers are still not really aware of the benefits of choosing plastic parts that they can’t get from using
metal parts.
Plastic isn’t only extremely durable and extremely reliable; it is also far cheaper than metal. It can save you quite a lot of money in construction costs.
This is due to the far lower cost of making plastic parts in comparison to metal ones. If you want to know more about the benefits of choosing plastic parts
over metal ones then you are in the right place to find out. The following five reasons are some of the best justifications for choosing plastic parts over
those built out of metal.
1. Plastic can be Recycled
Another benefit of choosing plastic is that it can be recycled. Most other materials that can be used to make parts are either impossible or far too
expensive to realistically recycle. This gives plastic a unique advantage, as it means that when your plastic parts are no longer needed, they can simply be
recycled into something else; unlike most other materials, which you will be forced to throw away since they are either impossible or too expensive to
recycle. Because you probably also have plastic materials on hand already, this can save you in material costs. Thus, your existing materials can be recycled
into new parts. Not only that, but it can also cut down on how long it takes you to get new materials.
2. Plastic Has a Longer Lifespan
Plastic is also a good deal more durable than metal or any other kind of material, and will be subjected to much less wear and tear than what would be
experienced with the use of other materials. Not only will your plastic parts be able to last for years and years which will allow you to avoid having to
make time-consuming and expensive replacements and repairs since the long-lasting nature of the parts will make them much more durable than any other type of
material could possibly make those same parts.
3. Plastic is the Safer Option of the Two
Working with metal parts of any kind, there is always some risk of injury from, for example, the sharp bits. Plastic parts do not possess this risk factor
thanks to their lightweight design and smooth edges. If you are installing plastic, whether it is small or large parts, then you don’t have to worry about
things like injuries from sharp edges and the like as you would if you were installing metal parts instead.
4. Design and Increased Size Flexibility
Plastic offers you a greatly increased form of flexibility that metal is simply not capable of matching. Say you want to have a wider variety of different
options available to you. (For instance: what size your parts can be, exactly how they can be designed, etc.) Then plastic is a far better option than metal.
Plastic is a good deal more flexible; it offers you a significantly wider range of options. That’s because plastic can be molded into a wider range of
different shapes and designs than metal can.

Designing Tips for Injection Molded Plastic Parts

Plastic injection molding is used for everything from homeware to industrial parts . Injection-molded plastic parts prove their worth whether you’re designing a new product, or even a single component in a complex assembly. On the positive side, the injection molding process ensures quality and uniformity. However, tooling a mold is expensive, and small errors can have big consequences. Here are some tips Jingwei industry has gleaned from decades’ worth of experience helping our clients get it right.
Keep it Simple
The simpler your part design, the better. Keep in mind, however, that what seems elegant on the drawing board, or in a CAD program, may not work as well in the real world.
Embrace Uniformity
Uniformity of wall thicknesses in an injection-molded part or product ensures optimal flow during the molding process. This, in turn, leads to a consistent product. We will help you determine proper thickness to optimize product quality.
Avoid the Sink
Sink is a phenomenon whereby the plastic shrinks as it cools and does not cool evenly as it sets. If one area cools more slowly than the rest, you’ll notice warping and indentations. Using a thinner wall size, as well as proper sizing and placement of functional elements like ribs and ramps will minimize the possibility of this occurring.
Transition Properly
To begin with, design your mold so the plastic flows from thick to thin. If you have a section where the wall thickness tapers off, the tapered end should be farther from the injection site to ensure uniform quality. You should also learn to love curves. Sharp corners and transitions mean stress that’s literally built into your parts. This can mean warping, deformation, and premature wear. Using smooth radii and carefully working draft angles into your parts will ensure a better molding process and parts that are more durable.
Understand Your DFM
DFM, or Design for Manufacturing, reports are how the manufacturer highlights potential concerns with the molding process. There are times when the mechanics of injection molding can cause function issues with your product. Our goal is to identify, and help you address these issues before the mold is tooled.
The points listed above are only one facet of a larger process. If you’re in the early stages of designing and prototyping a product, you will also need to consider the types of plastic used, the scale of your production run, and whether plastic injection molding will be right for your project. When it comes to getting a handle on the process as a whole — from initial prototype to return on investment — Jingwei industry brings to each client and each project proves its worth. Take time to contact us for a free quote and be sure to ask us about our free offer.

Keys to Successful Mold Making

The key to a successful and precision part depends on the quality of its mold, but building a reliable, long-lasting mold can take a considerable amount of time — and requires a great deal of accuracy. Also, molds are often one the largest capital investments in a project, so it’s critical that tooling
is built right the first time around. This is particularly important in high-volume injection molding projects, where molds can be extremely complex.
Below are some important factors to keep in mind when building a mold to ensure optimal quality and reliability.
What Makes a Good Mold?
A high-quality, precision-engineered mold that is built to last can be an excellent investment for your company. The best plastic injection molds feature all of the following characteristics:

1. Good design and engineering
2. High-quality stainless steel mold bases and cavities for optimal performance and durability
3. Manufactured on modern equipment with the capability for precise machining
4. Accurately crafted with attention to high standards and tight tolerances

How Does Our Factory Make Molds?
To create a mold, we reverse engineer a design from a supplied part or create a mold based on the customer’s drawing or CAD file. To craft the tool, the team then utilizes EDM equipment, CNC mills, lathes, and grinding machinery. Many of our designers started out as toolmakers, so they fully understand the intricacies of the process, from start to finish.

New Plastic Product Development Process

Below we list a fairly standard sequence of steps that you will probably have to go through in the course of designing and making a new product.You can use it as a checklist to make sure you don’t overlook some vital step when planning the work, or when it has begun.
Step 1: Product Concept
This consists of basic sketches around your product idea. So ask yourself -what is your product and how is your product going to be used?
Step 2: Research
It is vital to research the current markets and demands. So you need to find out what is already on the market what is similar to your product idea? If there is a similar product, how is yours going to be better?
Step 3: Product design development
Using the information you have gathered from your research you can now develop your product designs. When you are designing your product need to answer the following questions:

• What is the function of my product?
• Will my product be able to withstand use?
•  Will the manufacturing process be easy to produce the final product? Does it contain multiple parts?
•  Will the process be cost effective? Can you still make profit after manufacturing your product?
•  Do you want your product to be of a high quality?
•  Can your product be maintained or will it break after one use?
•  Which material will your product be made from? This will depend on the use and the forces your product is expected to withstand.

Step 4: Research and development of the final design
This is the final tweaks to your drawings with dimensions and material selection so when you progress to step 5 you have a detailed drawing to work from.
Step 5: 3D model
Using 3D modelling software (CAD – computer aided design) you will get a computerised 3D model of your final product design. These designs will often highlight problem areas where the theoretical stresses and strains on the product will be shown. If there are problems now is a good time to address the design faults and revisit step 4.
Step 6: Prototype
A prototype of your design will be created using computer aided engineering systems.
Step 7: Prototype Testing
This is the point where you may have to go back to the drawing board when you test your prototype. Be critical – will your product function properly? If your product isn’t right, go back to Step 3 and re-develop your designs.
Step 8: Manufacturing
Once you are happy with your product prototype you can then manufacture your product! Manufacturing costs depend on complexity of your product, if there are multiple components, material selection, low batch product or high batch numbers. These factors need to be considered to ensure you will make a healthy profit on your end product.
Step 9: Assembly
The assembly of your product is vital – It is recommended that your product should have the minimum number of joins; this will not only spend up manufacture and reduce manufacturing costs it also makes assembly of your product quicker. So the overall costs of your product will be considerably less than a complex product.
Step 10: Feedback and testing
Test your final product with family, friends and focus groups. Again it is important to be critical of your product and listen to the feedback you get back from other people. This will help with any further product development.
Step 11: Product development
If your testing and feedback have highlight areas that need improvement, you will need to revisit your product development – most manufacturing companies would have flagged up obvious issues before you get to this stage so at this point you are just tweaking or you might be skipping straight to Step 12.
Step 12: Final Product
You now have your final product so you need to focus on your marketing campaign and how you are going to sell your product. Remember, the more you sell, the larger the manufacturing batches, the lower the cost of manufacture  means more profits!

4 top design considerations for the injection molding process

When you are preparing designs for the injection molding process, there are many factors to be taken into consideration. As a leading manufacturer of thermoplastic injection molded parts, we have the experience and knowledge of what makes a great design for the production of outstanding products.
As you begin the design process, there are important details to keep in mind. Plastic injection molded parts offer many advantages. The following are the top design considerations for the injection molding process.
1. Draft.This is the first and probably most important item to consider. Draft is what helps eject the part from the mold. Stuck parts, or parts that need to be forced out of the mold, are often damaged or distorted rendering them useless. To facilitate mold release, draft angles must be calculated during the design phase and customized for each part.
2. Wall thickness.When designing a part, minimum wall thickness must be considered. The thinner the wall the less plastic is required. Cycle times will be shorter because parts cool faster. Ideally, parts should be designed with the thinnest walls possible while still maintaining the integrity of the part.Uniformly thick walls offer the best possible outcomes in terms of reducing warping and maintaining quality. When wall thickness varies, filling the mold is more difficult and leads to stresses at boundary areas. If uniform wall thickness is not possible, a gradual taper is the best design option.
3. Wall strength.To strengthen the walls of the part, ribs are a vital consideration. During the design process, the thickness of the ribs must be in proper proportion to the walls. The height of the ribs, their orientation, and incorporating draft angles are aspects that must be taken into consideration when creating part designs.
4.Know your materials.  Material selection is one of the most critical considerations in designing your piece — it factors into many aspects of the process, including shrinkage factor, cooling time, flexibility and more. Different materials can have different minimum and maximum wall thicknesses, for instance, or can require different degrees of draft.
Although we have highlighted the top four items to consider when designing parts for plastic injection molding, there are many, many additional considerations. Jingwei molding has more than 15 years experience in mould design and making.
