Causes of dents in mould processing of automotive plastic parts

Plastic mould processing as a processing technology, after its production or completion, there will be some bad situation. How to solve this problem?
 
The causes of dents are as follows:
1) Insufficient cooling of the mould and insufficient cooling time will cause serious deformation.
 
2) Insufficient internal pressure of the mould will also occur.
 
3) The thickness of each part of the product is different. In this case, the overall treatment method is to reduce the barrel temperature and mould temperature, force cooling in the […]

Is there a company that offers quality custom plastic injection molding services in Shenzhen or Dongguan China?

Not all companies that plastic injection molding can meet the needs of their customers.
Sometimes, a company can not offer a complete service to a client because it has certain limitations, either of space, speed of manufacture and also of the customized creation of the requested design.
The companies involved in plastic injection molding know that sometimes customers request certain types of elements that are outside the standards they have in their most common designs, therefore, many of these have been […]

How to Identify The Quality of Injection Parts

From three points, we can see the quality of injection parts.

First, look at the appearance
 

Seewhetherthe injection parts are complete and whether they are deformed or not;

 

Whether the injection parts are uniform in color, whether there is obvious color difference, and whether the color is bright and translucent.

 
Second, touch the product
 

Touch the the surface of the injection part to see whether smooth, and whether there are burrs around the handle;

 

Whether theinjection parts have been naturally aged, the aging is reflected in […]

Rapid Prototyping China: Methods and Types for Prototype Manufacture

CNC prototype manufacture

With the numerical control process technology of CNC machining center, it can precisely process on materials of ABS or PMMA to produce transparent rapid prototyping prototypes with high intensity.
 

Laser rapid-prototyping prototype manufacture

In accordance with parts’ geometrical information generated by CAD, it can control three-dimensional numerical control system and use laser beams or other methods to heap up materials to form laser prototype.
 

Product silicone casting prototype manufacture

Using CNC prototype or laser prototype, as well as reverse manufacture silicone mould, it can manufacture small amount of transparent […]

How Does Prototyping Work With Designs

By using a rapid prototyping service, you can save time, money and effort by both the company and the client. Prototyping China ensures a superior-quality finished product by the help of this advanced technology. One thing that makes rapid prototyping services unique is that no tooling or machining is required to create 3D models.
 
Different parts and components are made as samples through prototyping services. Rather than going for a direct mass production, rapid prototyping services assist design engineers in efficiently perfecting their designs in advance of production.  The […]

Six Common Polishing Methods for Plastic Mold

here are two main purposes for polishing the mold, one is to increase the brightness and beauty of the plastic mold. The two is to make the die easy to die out. In the process of polishing, crude oil stone is used for rough grinding of the machined mold cavity surface, grinding to the tool mark, and then using the fine oil stone to get the coarse oil stone to reach the trace, then the fine sand paper is […]

Four Critical Questions To Ask When Finding An Injection Mold Manufacturer

Sourcing An Injection Mold Manufacturer
Choosing an injection mold manufacturer that you trust can be the most difficult, but the most important decision you make for your business. Asking questions is one of the best ways to determine if you and a potential company are a good fit. Making sure a company can handle your request and accomplish it in a reasonable period of time is key. Quality and budgets are also key factors to ask about.
Here are four important […]

Hot runner of injection mould

In order to simplify the injection molding process and reduce the waste of parts, it is important to eliminate the need for a large auxiliary cold runner. The key is to ensure that the melt remains molten throughout the flow channel system so that it does not solidify until it reaches the cavity wall where the cavity is cooled.

Internal heating hot runner:
The internal heating hot runner system is the first hot runner system to be put into the market. […]

HOW ARE PLASTIC INJECTION MOLDING PRODUCTS MANUFACTURED?

Plastic is the most versatile material that is used in most applications today. The wide range used of this material has made a great impact in most industrial world. One of the processes in creating plastic product today is called plastic injection molding.
Plastic Injection Molding is a process that has been rapidly growing and which has brought in more momentum within a short range of time. The process of plastic molding injection brings about quite a few advantages. The […]

Cold Runner of injection

The advantage of cold runner is that it is easy to use and can meet some aesthetic requirements. The cold runner reduces injection into transparent acrylic or polycarbonate parts used for light transmission, avoiding the visible banding effect of injection in some parts.

In addition to the waste of raw materials, the defects of the cold runner include adding steps to the whole automation or manual process. Removing the cold runner from the parts of the mold requires robots or […]
