Plastic injection mould Manufactured & suppliers

How to choose a qualified injection molding supplier in the motor industry?

Injection molding is one of the most popular manufacturing methods for the production of plastic parts in the whole world. It can mass produce high-quality parts with an accuracy of less than 0.02mm. Choosing incorrect parts will not only affect the quality of the final product, but also cause malfunctions, increased costs, and customer dissatisfaction. In order to ensure the consistency of quality, manufacturers must consider and control a series of parameters in the injection molding process, such as temperature, mold design and machine efficiency. In order to ensure that the motor plant has the highest quality parts, it is necessary to choose an injection molding manufacturer, who needs to provide expertise and technology at every stage of the process.

How to choose the right manufacturer

Customers looking for plastic parts manufacturers should pay attention to the content involved in the injection molding process and what level they expect from the part supplier at each stage. The motor manufacturer provides advice on application issues and asks whether the manufacturer meets the following requirements before ordering parts from the manufacturer:

Does the injection molding supplier have a good history and background in manufacturing the types of products that customers need? What is the company's manufacturing capabilities? What manufacturing and quality systems are there to ensure that high-quality parts are delivered at the correct cost? Have the precautions regarding its manufacturing capabilities, tooling, machinery and process control been addressed? Do you fully understand the manufacturer’s capabilities, quality control measures and employee capabilities? How about their quality measurement and on-time delivery performance?

By focusing on the processes and services provided by the manufacturer, you can ensure that the purchased parts are of high quality and can be produced efficiently.

Precision mold

Understanding the professional knowledge provided by the manufacturer at each stage helps to fully understand the injection molding method of its parts. The key to injection molding is the mold of the molded part. The development of the mold requires professional knowledge and experience to ensure that its accuracy is sufficient to avoid the final part. Defects such as burrs, warping or excessive parting lines. In the mold development process, excellent manufacturers should provide opportunities to provide trial samples, especially when customizing parts, so as to ensure that the mold produces consistent high-quality parts and design features.

Choose the right plastic

The required material properties of the part are critical to the tensile quality and aesthetic quality of the final product, for example, whether to look for a custom color, texture or quality (for example, need to be washable or strong). Some of the most common thermoplastics used in injection molding are: ABS, PA, PC, PP, POM. These can be heated and used to make parts, but they all have their own characteristics. For example, ABS is strong and chemically resistant, but not suitable for outdoor use, so it has become a popular choice for automotive interiors and computer equipment. In addition, PC is heat-resistant, transparent, and can be used in outdoor components, making it suitable for glasses, greenhouses or test tubes.

If they are compatible with each other, plastics can be mixed to combine different characteristics into one material, and resins of different colors can be added to the plastic to obtain the desired aesthetic effect. Under the advice of experienced manufacturers, the motor manufacturer and engineers should be able to find a material that combines the required materials with aesthetic qualities.

Efficiency of the injection molding process

The manufacturer's injection molding process should be efficient enough to quickly produce a large number of parts in a way that minimizes waste. Scientific molding is the key. It provides highly accurate process steps that can produce high-quality parts with consistent tight tolerances and repeatable dimensions.

Injection molders and injection machine manufacturers who are experienced in the application and use of scientific molding can help customers get rid of random injection molding mold design decisions and turn to data-based accuracy. It sounds very basic, but there are many factors that may affect plastic injection mold design, molding process and demolding. Engineers trained in scientific molding can easily identify and help prevent potential errors.

Reduce and recycle waste

Experienced manufacturers ensure that the right amount of plastic is injected under the correct pressure, and the mold design is reasonable enough to prevent material escape and reduce waste in the mold development stage. Some injection molding manufacturers recycle the nozzle waste by reheating it and mixing it with virgin plastic that can be used to make new parts.

The hot runner system in some machines keeps the plastic liquid between two injections, which saves energy, does not require reheating the plastic, and reduces the amount of wasted plastic, which helps reduce the cost of delivery to customers. And reduce the impact of the molding process on the environment.

Mechanical maintenance

Maintaining the machine to minimize downtime and delayed delivery is also essential. By choosing the correct type of injection molding machine and using predictive maintenance techniques, injection molding manufacturers can ensure maximum efficiency.

energy efficiency

By asking the original equipment efficiency parameters of the injection molding machine manufacturer, the mechanical efficiency can be quickly found. Most factories use Sumitomo Demags, which can achieve faster cycle times and stable processes. These machines also bring maintenance advantages. Compared with the old machines, it saves about 1 second in movement and opening and closing. Equipment manufacturers can also remotely video to see whether the machine is operating normally (if it has been calibrated), and provide recommendations for routine maintenance plans.

Choose a manufacturer with the right injection molding machine

The basic process completed by each machine is the same, but there are many variations in the types and specifications of injection molding machines. The machines can be operated by electric, hydraulic or hybrid power (combination of the two) to provide manufacturers with different mechanisms and efficiency levels . It is very important to choose a manufacturer with a high-efficiency injection molding machine. It may have a catastrophic impact on manufacturing. The efficiency is not high, the cost cycle cannot be reached, and unqualified parts will eventually be manufactured. By choosing the right machine, you can ensure the production of complex, high-quality, and stable-quality parts that can be delivered efficiently.

Maintain quality with Industry 4.0

Injection molding machines support Industry 4.0. Using these advantages, you can not only maintain the machine to achieve maximum efficiency and uptime, but also ensure that the parts have a consistent level of quality. Using 3D printers to help develop prototypes of custom parts, this technology helps reduce costs and improve the efficiency of the design process. It is not necessary to develop molds to test the design of parts, and a large number of samples for testing can be quickly generated. Installing robots and monitoring technologies in machines, such as predictive maintenance, can help maintain efficiency during the production phase. Moving towards smart factory technology is essential to ensure the future development of products. 3D printing means that samples of products can be obtained on the same day instead of waiting for a week.

in conclusion

It is important to find a manufacturer that can produce the required number of parts and deliver them quickly. The quality of the parts is important to ensure that international and industry quality standards are consistently met. In the long run, qualified injection molding manufacturers can not only avoid unnecessary troubles, but also ensure that the production schedule is not delayed, avoid the resulting cost waste, and strictly control the process from receiving orders to manufacturing and shipping to customers. aspect.
