Everything You Should Know About Injection Molding Parts

Almost every industry benefits from using injection molding technology. It is an affordable, consistent, and reliable way of applying complex injection molding parts. Though you can see them anywhere from car parts to a tiny hub, their production condition is quite complex to have a deep understanding of. Injection molding is the standard method of producing plastic parts these days. But some require more finesse than others. Not all manufacturers have what it takes to deliver specialized injection molding parts with stringent specifications. In this article, you will learn about the complexity of injection molding parts and how to pick an injection mold supplier who can provide them.

Applications Of Injection Molding Parts

Injection molding parts are prevalent in various diverse fields. Each field has specific requirements for quality and finesse. Here are some examples of their usage:

  1. Hospital Equipment

Plastic components are prevalent in hospital equipment. Many kinds of modules use injection molding parts these days due to their being more accessible. Examples include medical projection lamp housings, molded clear boxes, and clear light pipes.

Medical parts usually have precise requirements too. The projection lamp housings, for example, require certified high-quality raw materials. They also need to have zero contamination, requiring a specialized molding room.

The finished product needs high-quality polishing to ensure clarity. Its light also needs to be parallel.

  1. House Detecting

Detection devices come in many shapes and sizes and have different functions. But most of those devices use plastic housings. Those plastic housings are usually injection molding parts.

The detection devices need to have a robust constitution. They need both durability and flexibility. That’s why the hard and soft parts are molded separately in an over-molding process.

These parts also require premium quality plastic. However, they do not need any more extra detail.

  1. Automobile

The automobile industry uses many injection molding parts in its manufacturing process. These parts usually tend to be more durable but do not require delicate finishing. Oil pump manifold hub and ventilation housings are excellent examples of injection molded parts used in the automobile industry.

The oil pump manifold is a bit tricky because it needs metal insertion. So, the finished product has steel or other metal embedded in the hub. The high-quality oil pump manifolds need to meet DME or Hasco modular standards.

The ventilation housings are straightforward. The injection mold needs good quality materials and proper calibration to make them.

How to Meet the Quality Requirements for Injection Molding Parts?

As you can see from the descriptions above, injection molding parts can require a lot of expertise. Injection molding is a widespread thing these days. But that does not mean every manufacturer is equal.

Some manufacturers may fail to deliver the desired quality. So, finding a reliable injection mold supplier is essential if you want cutting-edge products. Only a top-tier supplier can meet some of the more stringent requirements.

 

How to Choose a Capable Injection Molds Manufacturer?

You must be clear about how crucial it is to find a good supplier. But finding a top-tier injection molding parts supplier is not an easy task. There are some essential rules to check before deciding if they are worth cooperating with or not.

Here’s a list of criteria you can use to judge them:

 

  1. In-House Production Capability

Some parts suppliers rely on outsourcing to build their inventory. These suppliers can never provide you with specialized products. Medical parts usually have special requirements for the production process.

You would need to find a supplier with in-house production capacity for that. They can adjust their production process based on your needs.

  1. Up-To-Date Production Facilities

Injection molding has been going through many stages of development since the day of its inception. The latest technology can offer more consistent quality without any material waste. High-performance CMM machines, CNC machines, EDM, milling, grinding, drilling machines, and injection machines – all of these up-to-date metal helpers will bring you satisfying products.

  1. Organizational Structure

Structure and discipline are necessary qualities for a reliable injection molding parts supplier. Poorly organized facilities can cause significant delays in delivery or even deliver unqualified products. Therefore, you are in need of finding an injection mold supplier who has a clear project flow and production schedule.

  1. Employees with Know-How and Competence

Lastly, the supplier needs to have competent employees. Incompetent employees can ruin a project even with the best equipment. Hence, you should pick a supplier that has a good track record.

Conclusion

The demand for injection molding parts is pretty high these days. But there are too many injection mold manufacturers out there, so it gets tough to choose a reliable supplier. So far, many clients have had an excellent experience with Abery. We are very reliable with our management, delivery, and, most importantly, high-quality products.

6 Tips to Avoid Cracking in Custom Plastic Injection Molding

Custom plastic injection molding requires a lot of attention to detail. It is common for cracks to appear on the molded part if one does not know how to avoid them. But knowing those can be difficult without a lot of experience in the field.

One needs a thorough understanding of the reasons behind the appearance of these cracks. Only then can they successfully avoid them. You will find everything you need to know about injection molding cracks here.

What Is Cracking in Injection Molding?

Cracks are not uncommon in custom plastic injection molding, and they appear on the products in different ways. Some cracks are more problematic than others – but all of them are equally annoying. There are internal cracks, corner cracks, and even cracks that start at the gate.

These cracks are exceedingly harmful to the molded object because they cause integrity issues. It gets even worse if you need to fit that molded part to something larger. A competent manufacturer should never allow a compromised piece to pass through their production line.

 

Reasons Why the Molded Parts Crack

Contrary to popular belief, the custom plastic mold design has little to do with the formation of cracks in molded objects. The true culprits of custom plastic injection molding are the ones we have listed below:

  1. Machine

The plasticizing capacity of the machine is a crucial part of crack-free injection molding. A low-capacity machine cannot handle mixing the inserted material volume, leading to cracks. An overly large machine will also degrade the quality as there is a chance of over mixing. So, select the right machine according to your production to ensure optimum efficiency.

So, be vigilant about the plasticizing capacity of your injection molding machine according to your production volume and type.

  1. Mold

The molds play a significant role in custom plastic injection molding. It is usually the most important thing after the main machine. A bad mold can mess up the ratio and distribution of the molten plastic. That will usually lead to cracks and other issues for the finished object.

Burrs and other undercut conditions in the mold can cause cracks too. Ejector designs can also be probable culprits. In other words, you need a professional plastic injection mold design for your products.

  1. Material

Material integrity is essential for custom plastic injection molding. The quality of a molded part depends heavily on the material used in the manufacturing process. High-quality material naturally produces better results.

Reclaimed or recycled plastics usually have lower quality. That can lead to cracks. The moisture content of the material also plays a role. Too much moisture can cause cracks during the cooling process.

  1. Molding operation

Some molded parts require more cooling time than others. A short cooling time usually causes cracks and other defects to these parts. That is also true for molding under too much pressure. Some plastic molds need to work under less residual stress to show the best result.

How to Avoid Cracking in Custom Plastic Injection Molding

Now that you know what’s causing the cracks, we believe you are ready to fix them. Follow these tips to avoid cracks:

  1. Remove Burrs

Burrs are always a nuisance. They can cause deformity and cracks if left untreated. Do a regular inspection to identify and remove burrs to get crack-free molded parts.

  1. Install More Knockout Pins

You need to distribute the stress evenly to avoid agitating any part of the molded object. Try installing more knockout pins. They should help maintain even stress.

  1. Use Less Reclaimed Materials

Reclaimed or recycled materials or pallets tend to have poorer quality compared to new plastic pallets. The reuse of plastic over and over again does slowly wear its polymeric structure every time it is reused.

So, using reclaimed plastics that have gone through too many cycles can cause imperfections in the finished product, leading to cracks. Reduce the amount of reclaimed material you use. If possible, avoid them entirely to get better results.

  1. Remove Moisture

Removing moisture content from custom plastic injection molding will reduce the cracking issue since the moisture inside the materials does harm to the full mixture inside the mold. Dry all your plastics before starting the process.

  1. Increase the Cooling Time

If your cooling time is too short, consider increasing it, and it will give you a much better result. A longer cooling time will keep the mold confined longer, leaving more time for the injection parts to fuse together. That will help create a better outer layer.

  1. Reduce Holding Pressure

Use accurate material volume to reduce the pressure of the molding process. Less pressure will reduce the cracking. You could try with a 50% holding pressure to get a uniform packing. Holding pressure is usually set around 70% for most projects.

Conclusion

Custom plastic injection molding depends a lot on the materials and tools you use. That’s why we always advise people to look for the best plastic injection mold supplier. We at Abery use the latest technology to create the best injection molds in the industry that ensure 100% crack-free injection molding.

Process of Producing a Custom Plastic Mold

There is a step-by-step process to making plastic injection molding parts. And as with most things, it first starts with the design.

  1. Mold design

The mold design process is crucial——Here is where you hash out all the ideas and talk about the different needs for your project. A poor design can ruin your custom plastic injection molding project. And it will also cost more compared to a well-designed DFM design.

  1. Mold manufacture

After the design process, it is time to manufacture the mold, where the expertise of a molding supplier usually shows. There are mainly five steps to produce a mold:

  • CNC machining: In this procedure, the digital milling machine uses a rotating cylindrical tool to cut workpieces accurately, versatilely, and fast to get the desired shapes.
  • EDM machining: EDM machining stands for electro-discharge machining or spark-machining. In this process, a particular shape is obtained by using electrical discharges. This process is also called wire cutting.
  • Lathe Machining: Lathe machining is a precise machining procedure. It can perform operations like changing the surface roughness, weak resistance, visual properties, and chamfer the mold’s features.
  • Mold Fitting: This is one of the most critical processes of custom plastic injection molding. It requires expertise where mold pieces are put together to form a perfect shape or mold.
  • Mold Polishing: This technique helps increase the smoothness of the mold and makes the products easier to demold. That can be done by horning which is usually conducted by whetstone, sandpaper, polishing paste, and wool wheel.
  1. Mold Trials

The last stage in the custom plastic injection molding process is mold trials. You need to make sure that the mold you designed and manufactured works perfectly and as intended.

Without any trials, you might overlook critical and non-apparent design or manufacturing mistakes, which can be very costly down the line.

Plastic Injection Molded Parts Quality Control 100% Inspection

100% plastic Injection molded parts quality inspection methods
In China,Whether produced after injection products meet quality standards, must be tested, a common quality test methods are the following few ways.

injection molded plastic in china
injection molded parts inspection in china

full inspection
It was called full inspection is individually tested for injection products, we have talked about “full” refers to the number of all the plastic parts produced, rather than the entire value of the quality characteristics tested. In determining the test items,Test costs are generally low, the implementation of all product inspection is to have a higher quality requirements.

Such as plastic parts Dimensions test is easier and can be fully tested, and the requirements of the position and some plastic parts crucial, a great impact on the quality, but also the need for full inspection. Not plastic parts for each test must be carried out in full, as it cost too much time-consuming and laborious. Usually occurs when the following conditions using full inspection.

1) found that more unqualified plastic parts, plastic parts or the whole batch are unqualified, the need for follow-up products for full inspection.

High single value

2) injection products, even when a scrap will bring great losses.

3) If the product quality problems, give people life safety or safety hazard when great.

Injection molded plastic sampling inspection
The so-called sampling inspection,, is from a group of randomly selected plastic part of the test conducted. By this test section of plastic parts extracted to make the evaluation of quality of these plastic parts. Compared with the full inspection sampling inspection, it tested a small number of plastic parts, low-cost test, test speed. Sampling inspection and batch size of the number of samples, volume, sample quantity; small quantities, less sampling; as long as the appropriate number of samples, the test results have a high accuracy. Usually by random checks in the following cases.

1) Some of the Injection molded plastic parts that mechanical and physical properties need to destructive testing, this will bring damage to the plastic parts.

2) more than the mass production of plastic parts, plastic parts produced quantity particularly large, want to save test time and test costs.

3) the production of raw materials in Injection molded plastic parts, there are a lot of raw material is powdered, granular or liquid form, the raw material for these multi-use sampling. Compared with the full inspection sampling inspection, although there are a small number of test and low test cost advantages, but also the following problems: First, when the second installment of the plastic parts, even after sample testing has been considered qualified, can not believe that this batch of plastic parts plant each plastic parts are qualified, which may also exist a very small amount of non-conforming product. Second, the sample tests will inevitably appear judgmental errors, this is the vast majority of qualified products, due to sampling bias, but judged unqualified; or could have been substandard goods, has become qualified. Therefore, in order to determine the probability of error is controlled within a reasonable range, often need to coordinate the use of mathematical statistics methods.

In short, the full inspection and sampling test has its own characteristics, and applications and problems also vary, depending on the circumstances test methods should be chosen to adapt. Mostly due to the injection mold products for mass production, it is more to take sample tests

Machine Inspectioninjection molding molded plastics inspect
Parts are initially inspected directly out of our molding machine. Our engineers are trained to identify and rectify the following defects:

Sink marks that form when the outer plastic shell hardens before the internal plastic has had an opportunity to cool
Short shots caused when there is an inadequate amount of plastic material to fill the mold
Burn marks caused by trapped compressed air during the molding process
Flash marks, which is the excess plastic that extends from the end of the molded part.
