What are the effects of wall thickness of plastic products on quality

The wall thickness of the plastic parts processed by injection moulding has a great influence on the quality. When the wall thickness is too small and the flow resistance is too large, it is difficult for large and complex plastic parts to fill the cavity. The minimum size of the wall thickness processed by plastic parts should meet the following requirements:
 

It has enough strength and stiffness.

 

It can withstand the shock and vibration of demoulding mechanism when demoulding.

 

Can withstand the […]

China custom plastic injection molding services and additive manufacturing at your fingertips for large volume of manufacturing

Although many companies can mold in a personalized way, they are not able to satisfy the growing demand of customers.
There are several companies that offer custom injection molding services, but none can satisfy a great demand because they do not have the number of machines necessary to manufacture all the products requested in a short time.

The custom injection molding services must be completely oriented not only to the quality, but also to the quantity of pieces that can be […]

What Is A Short Shot In Injection Molding?

A short shot is the incomplete filling of a mold cavity which results in the production of an incomplete part.
If a part short shots, the plastic does not fill the cavity. The flow freezes off before the flow paths have completely filled.
To ensure the finished part is of good quality, the part must also be adequately packed with plastic. Therefore the question to ask is not only, “Will the part fill?” but also, “Can a good quality part be made?”
Causes

Flow […]

How to maintain automotive plastic parts?

Automotive plastic parts are used more and more widely. Automotive plastic parts are not only cheap, but also environmentally friendly, beautiful, convenient and durable. Nowadays more and more automobile metal parts are replaced by plastic parts. In order to ensure the normal operation of various parts, the maintenance and maintenance of automobile plastic parts are also very important.
 
Maintenance methods of automotive plastic parts:
 

Inspection: Deformation and damage of automotive plastic parts are determined by inspection.

 

Fastening: Fastening is an important maintenance […]

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 Spin Casino app 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,
casino online url 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 […]
