Plastic Injection Tooling

Suggestions On The Maintenance Of Injection Molds

Compared with other moulds, the structure of injection moulds is more complex and precise , the operation and maintenance of the product requirements are higher, so in the entire production process, the use of positive solutions and careful maintenance, maintenance to maintain the normal production of enterprises, improve the efficiency of enterprises, has a very important significance.
 

Select the appropriate molding equipment, determine the reasonable process conditions, if the injection molding machine is too small to meet the requirements, too […]

How long does injection molding take?

The main determinant is the total number of products that customers need to produce. It takes about the same time to produce a product. Multiply the time to produce a product by the total amount of production the customer needs to produce to figure out how long it takes.
 
Material and machine preparation time should also be taken into account before formal production. The preparation time of the machine is very short, because the equipment of the injection moulding factory […]

Welding Line In Plastic Injection Molding Process

Weld Lines
The flowing defects on product surface or the linear defects that are caused when melt fronts meet each other after splitting.
Weld lines refer to the lines that occur on a plastic product surface when the cold slug melts. In areas of mold cavity where the molten plastic meets inserts or holes, areas with inconsistent flow speed/flow interruptions, where multiple flows meet or when jetting happens during mold filling, linear weld marks tend to occur due to imperfect bonding. […]

Requirements of Plastic Material for Automotive Injection Molding Parts

Excellent weather resistance, guaranteeing long-term use without color, aging cracks (including heat and oxygen aging and light aging);
 
Good chemical resistance, to resist the erosion of oil and daily chemicals;
 
Easy moulding, the injection grade material should have enough fluidity to ensure the moulding of complex components and improve production efficiency.
 
Economy requires material with high performance-price ratio.
 
Material requirements for exterior accessories
 
Weather resistance: Weather resistant materials such as AES, ASA (AAS), PC/PBT (PET) should be selected for parts that are not coated […]

Five Steps Of The Injection Mold Production Process

 With the continuous development of automotive electronics, higher requirements for product modeling,
JasonMould here shares the five steps in the injection molding process.
1. The mold structure design
A set of high-quality molds requires not only good processing equipment and skilled mold making workers. Another very important factor is good mold design, especially for complex molds. The mold design accounts for more than 80% of the mold quality.
An excellent mold design is: under the premise of meeting the requirements of customers, the […]

What factors should be considered in the design of plastic injection moulds?

Injection cost

According to the size of the machine, how much per injection, so as to determine the product ranking mode and the number of holes. The more the number of moulds produced, the lower the cost of injection moulding. Because the cost of injection moulding is calculated according to injection order.
 

Product Appearance

According to the product appearance requirements, determine the parting surface. The position of parting surface should be beneficial to die processing, exhaust, demoulding, etc. The more products, the greater […]

Injection mold development cost and how to identify a high quality mold.  

 
What is the injection mold?
Injection mold is a tool for producing plastic products; it is also a tool for imparting complete structure and precise size of plastic products. Injection molding is a processing method used in mass production of complex parts of certain shapes, specifically refers to plastics that melt by heat from injection molding machines.
High pressure is injected into the cavity, and after cooling and solidification, a molded article is obtained.
Mold application:
Mold is the basic process equipment for […]

What Plastic Parts are on The Car?

Bumper housing

Also known as “bumper”, but in fact it is only the auxiliary shell outside the bumper, not the body of the bumper. Bumper housing plays the role of cushioning and energy absorption, the working environment is relatively complex, and the volume is larger, so it is generally made of polypropylene (PP), because of its lighter weight and better corrosion resistance.
 

dashboard

 
Apart from wood and leather, the dashboards of automobiles are basically plastic, but there are differences between hard and […]

Requirements for selection of materials for injection molding parts

The selection of mold materials is an important issue in mold design and manufacturing, which directly affects the manufacturing process of the mold, the service life of the mold, the molding quality of the plastic parts and the processing cost of the mold.
Because of this, domestic and foreign scholars have developed new mold steels with good performance, processing performance and heat treatment deformation, such as pre-hardened steel, new quenched and tempered steel and maraging steel.
In addition, in order to […]

Does 3D Printing Replace Traditional Mould Manufacturing?

In recent years, with the development of industry 4.0, the manufacturing industry in China is developing rapidly from “manufacturing” to “intelligent manufacturing”. 3D printing technology has been widely used in China’s manufacturing industry. 3D printers can provide efficient and low-cost support for die design and manufacturing. Even with the rapid development of 3D printing technology, in some areas, it has gradually begun to subvert the die technology, forming a direct competitive relationship with it.
 
“Compared with 3D printing technology, traditional […]
