Accurate Custom Injection Molding? A Complete Guide


Plastic injection molding is a process utilized for the production of molded components. This process is known as accurate custom injection molding. It is the most sophisticated type of plastic molding that's used in the market. Although precision molding is commonly utilized for the production of plastic components, it is not used for the development of finished products.


About Accurate Custom Injection Molding

Unlike conventional injection molding, precision injection requires the use of precision machines and molds. This process is used for the development of complex plastic parts with precise shapes.The precision of a part is largely dependent on the precision injection mold and its suitability to meet the design engineering requirements.


Precision Injection Mold

The precision of the mold is a result of various factors including:

● Accurate position of the cavity

● Precision of the mold cavity size

● Choice of materials

● Precision of parting surface

● Number of cavities in the mold design

● Dimensional tolerance of general precision moulds

● Runner size

● The thickness of the bottom plate, supporting plate and cavity wall

● The material of precision mould (preferably steel aloys with high mechanical strength)

● Design engineering


How Does Precision Molding Work?

The process of molding plastic by CNC machining into an exceptional price and calculated shapes is known as polymer optics. As the technology of plastic injection molding continues to improve, industries that deal in specialized products such as medical devices, automobiles, and information technology will benefit from the process.


Following are some additional pointers about precision molding by molding consultants:

This process is also beneficial for the contract manufacturing of scientific and technical products. Although it's commonly used for the development of optical components, the precision injection process is not the right method for many high-end products. Through the development of new technologies, such as precision injection molding, plastic manufacturers can now offer their customers affordable plastic equipment. The use of polymer optics in precision injection allows the development of high-quality plastic mold designs. Before, products such as these were developed by molding consultants and experts. Now, they can be mass produced at a low cost. Integrated optical and mechanical capabilities are also key to the success of precision injection. One of the main features of precision injection is the low weight designing. This process allows the development of low weight components that are lighter than their original size. This process can be completed in one simple step, which means it saves time and helps in developing new products more accurately. Since the cycle time of precision injection machines is lower, it allows for faster mass production of plastic components. In addition, precision optics can also be combined with polymer to enhance the precision of a product.


Automation Potential

This process is widely celebrated for its ability to use automation technology. Through computers, it can be automated, allowing for the customization of batches. The process of precision engineering is carried out through cells that can perform various tasks, such as plastic injection molding. The mechanical properties of precision injection molding are highly customizable. It can also install and remove various mechanical components such as lens mounts and snappers.


Surface Specifications

There are certain limitations to the utility of precision molding because of the manufacturing technology. For instance, a 1mm to 100 mm diameter lens can be produced using polymer optical components. The thickness of the lens should be between 1 to 30 mm.


Tips and Tricks:

If you are planning to use precision molding for the development of your product, then you should carefully consider the various factors that will affect its utility.


Areas of Precision:

1. Tolerance Issues:

One particular factor that affects the process of precision molding is the tolerance of the product. This characteristic ensures that the exact requirements of the product are being followed correctly. The use of precision scientific molding avoids the risk of damaging the parts that are produced through this process. This process is also used for developing special parts that are not compatible with the overall machine.Precision molding will only be applied to the parts that are connected with other parts so that they are fixed in the correct form. Before you start using precision molding, make sure that you understand the requirements of the product. Not only does the product need to be designed with the exact tolerances, but it also has to be produced cost-effectively. The best solution is to enquire which parts of the product require precision molding and then conduct precision molding accordingly. Usually, the parts that require precision injection are molded following the development of the product.The required tolerance is achieved through precision molding.


2. Materials:

The materials used for precision molding are different from those used for other processes. If the molding process produces a high shrinkage capacity, the plastic will shrink during the production process. In terms of polymers, one commonly used material is polyethylene, which has a high shrinkage range. In addition, the use of plastic resin will affect the quality of the finished product. Generally, a good alternative is Acrylonitrile Butadiene Styrene.

ABS is a thermoplastic polymer that can resist the high temperatures and is considered an appropriate material for precision molding. In order to achieve a high shrinkage rate, the plastic should be mixed with a resin that's designed to absorb the excessive heat. Although induction of a material into a product does not guarantee that the product will not shrink, it can still cause the product to shrink.After achieving this process, a product development plan can be created to prevent the product from getting damaged during the production process.


3. Technique:

The process of precision molding requires that every piece of the product is developed identically and will be attached in an identical manner. If the product's design is not identical to the mold design, then the precision product will not be accurate. When you are in need of a precision-molded product, make sure that the manufacturer understands this aspect of development. A good precision molding company will take the time to learn the process and will not use rapid tooling techniques. This is the main idea of precision tooling and we hope to have covered all the basics.
