Many customers often encounter these problems when they are looking for injection mould suppliers in China:
  1. Communication problems: Language barriers, different terminology, little or bad English skills for engineers.
  2. Cultural differences: Eastern and Western business practices can be very different, often leading to misunderstandings, errors, poor quality and delays.
  3. The empty promise: Sometimes you go to the injection mould factory and you will find that they can't provide what you need. When you need it, they don't have the technology or resources to provide you with the quality you want. Many countries have backward infrastructure and communication equipment. As a result, the product cannot be delivered on time.
  4. Quality certification: ISO certification is an expensive and time-consuming process. Many mould factories are not qualified in Asia. They do not have quality control systems. They do not have the proper technology or experience in producing products. They cannot cooperate according to your specific specifications and timetable.

Moulds are widely used, and the plastic injection moulded parts in modern manufacturing requires almost all of them. Therefore, the mould industry is an important part of the national high-tech industry and an important and valuable technical resource. Optimize the system structural design of the plastic injection mould and the CAD/CAE/CAM of the profile, and make it more intelligent, to improve the plastic injection moulding process and mould standardization of the injection moulded part. Improving the precision and quality of the plastic mould manufacturing, and reduce the amount of grinding and polishing of surface of the mould part and injection mould manufacturing cycle. Using special materials with high performance and easy-to-cut performance for various types of mould parts to improve mould performance to adapt to market diversification and new product trial production. Applying rapid prototyping technology and rapid moulding technology to quickly manufacture plastic injection mould or die-casting mould, etc. All of them will be the development trend of plastic mould manufacturing technology in the next 5 to 20 years.
The time required for a plastic, such as nylon, POM, PC/ABS, to complete once injection moulding process is called the moulding cycle. It mainly includes injection time and cooling time.

The injection moulding cycle directly affects labor productivity and equipment utilization. Therefore, in injection moulding manufacturing, the relevant time in the moulding cycle should be shortened as much as possible under the premise of ensuring plastic parts quality. Injection time and cooling time are of the utmost importance throughout the moulding cycle and they have a decisive influence on the quality of injection moulded parts. The feeding time in the injection time is directly inversely proportional to the feeding rate, and the feeding time in injection moulding is generally about 3-5 seconds. The holding time in the injection time is the pressure time of the plastic in the cavity, which accounts for a large proportion in the whole injection time, generally about 20-120 seconds (the extra-thick parts can be as high as 5-10 minutes).

With the development of automotive industry, plastic parts have become important part of automobiles. In developed countries, the amount of plastic parts used in automobiles has even become an important indicator of the level of automotive design and manufacturing. We can't list all the plastic parts on the car. Just list a few important automotive plastic parts. Maybe you don't know they are plastic parts.
Automobile plastic Parts
The bumper shell should be the most grievous automobile plastic parts. Many consumers mistakenly think that it is the body of the bumper. The main function of the bumper casing is cushioning and energy absorption. Due to the complicated working environment and large volume, it is generally made of polypropylene (PP) with good quality and good corrosion resistance.
Whether the selected injection mould factory regards you as an important customer, that is, whether they value you, this is very important. In fact, looking for a supplier is like looking for an object, but also paying attention to the door-to-door. If your own company's financial strength is not strong and the order amount is not big, blindly choose large-scale mould factory cooperation, sometimes the money spent on them, but they don't take you seriously, at present many large injection mould factories are not responsible for the small orders, because you can't reach their requirements in terms of order amount, it will give you the feeling of taking a hot face to touch people's cold butt, this metaphor may not be appropriate, but it is also more relevant and realistic.
Injection mould

In this case, most people will choose small and medium-sized injection mould factories. After all, the price of injection moulds and plastic products is more acceptable. But soon you will find that worrying things are coming again. Can the injection mould be completed on time? Can the quality of injection moulds be good? What is the mass production of the injection mould? What is the life of the injection mould?
To meet the needs of demoulding of the plastic part and the condensed material in gating system and the need of inserts installation, the mould cavity can be appropriately divided into two or more parts, these touch surfaces that can be separated is called parting surface. In the case of poor mould making and insufficient clamping force, the molten plastic in the injection mould will be extruded through the parting surface to form rather thick flash. Although modified, there will be still obvious marks. Parting surface has various types, and the common ones are horizontal parting surface, step parting surface, oblique parting surface, and special parting surface. The parting surface is generally flat, but sometimes it is necessary to use curved surface and stepped surface for the purpose of convenient demoulding. Although the parting surface processing is complicated, the processing of cavity will be easy.
Plastic products have been widely used in automobile, mechanical and electrical, instrumentation, aerospace and other national pillar industries and related to people's daily life. Although there are many forming methods for plastic products, injection moulding is the most important method. In the world plastic mould market, about half of plastic mould output is injection mould. In recent years, the injection mould development in China is very rapid, and the proportion of injection mould with high efficiency, automation, large, micro, precision, high service life in the entire injection mould production is larger and larger. From the perspective of injection mould design and manufacturing, the development trend in China of injection mould can be divided into the following aspects.
Mould is the mother of industry. As the precursor of the mother of industry, the importance of mould steel to injection moulds is self-evident. And the cost of injection mould is also derived from the mould steel, because the injection mould manufacturer also quotes the price of the mould according to the price of the materials that mould use, such as the material coefficient method: plastic mould = 6 * material fee.
Calculate with experience:
Injection mould price = material fee + design fee + processing fee and profit + value added tax + mould trial fee + packaging transportation fee
How to find a reliable professional injection moulding manufacturer with reasonable price in China has been a concern of many customers. Many customers will worry that the quality of plastic moulded parts doesn't meet the requirements, and the delivery time won't be on time. And there are so many injection moulding companies on the internet, they don't know which is the most formal and reliable, which is most suitable for them. For these questions, ACO Mould will provide you with some ideas.
How to reasonably choose plastic injection mould steel has been complicated system engineering, and also the key link of plastic injection mould making. It is an important work related to mould service life and plastic injection mould cost. In general, the material used to make plastic injection mould is required to have certain hardness and wear resistance at first. Secondly, it should have strength and toughness. The next is easy to machine. ACO Mold is professional injection moulding manufacturer which produce plastic injection mould and plastic parts.
Injection mould is a tool for producing plastic products, it is also the tool that gives plastic products complete structure and precise dimensions. With the rapid development of plastics industry and the promotion and application of plastic products in the industrial sectors such as aviation, aerospace, electronics, machinery, shipbuilding and automobiles, the requirements for moulds are becoming higher and higher, and traditional mould design methods are unable to adapt to today's requirements. Compared with traditional mould design, computer-aided engineering (CAE) technology has great advantages in terms of improving productivity, ensuring product quality, reducing cost and reducing labor intensity. Today, our lives are closely related to plastic products, and plastic moulds are the most important and main tool for producing plastic products. Therefore, the price of plastic injection moulds has become an aspect of increasing concern.
With the rapid development of plastic moulding manufacturing industry, how to reduce the long development cycle and high cost of injection moulds has become a new goal that everyone is pursuing.

Now China has a low level of casting and it is difficult to achieve mixed casting. For the flanged moulds, high hardness and wear-resistant materials such as GM series, MoGr alloys, and air-cooled steels are generally used in the working part materials. By adopting a mosaic structure and satisfying the high life requirements of injection mould, an integral insert or an integral insert can be selected according to the size of the parts required in the working part.
