What will be caused when injection mold testing in many times?

The design of the injection mold was not fully collectively reviewed, and the structure of the injection mold was unreasonable, which caused the injection mold to undergo multiple improvements after the test, which made the injection mold cost exceed the budget.
If it can be solved after several improvements, it is relatively fortunate. There are many cases that are unsatisfactory, and even the injection molds have to be scrapped and reworked. This cost cannot be controlled.
There are also cases where […]

Why plastic parts have deformation when processing

In order to ensure the normal processing of plastic parts, operators need to understand the cause of the abnormal appearance in this process, the better to avoid the abnormal appearance during processing. Below, JasonMould share you the causes of deformation in processing:
 
 

During the process of molding, the surplus material is spilled into the gap between the mold and the mold surface and retained on the plastic part. A kind of linear trace on the surface of plastic parts, is […]

How to solve the surface sag in 2K mold

The basic reason for surface sag: from the perspective of plastics, when the plastic cools and shrink, insufficient filling will lead to product surface sag or internal cavity.
 
The causes and solutions of defects are different depending on the location of sag.
 

When the sag occurs at the final cooling position of the thick-walled product, or at a distance from the sprue:

 
Cause analysis: The typical thick wall and the surface sag or hole far from the sprue are usually due to […]

Causes and solutions for swelling and bubbling of injection molding parts

Some plastic parts after demoulding, have swelling or bubbling on the back of metal insert or in the extra thick parts. This is due to the expansion of the released gas under the action of internal pressure on the plastic which has not been completely cooled and hardened. JasonMould works with you for details.
 
Solutions:
 

Effective cooling. Reduce mold temperature, prolong tooling time, reduce drying and processing temperature.

Reduce the filling speed, reduce the forming cycle and reduce the flow resistance.

Increase the […]

Lettering on the surface of injection mold

We often see all kinds of patterns and Numbers on plastic pieces, and these Numbers are different. How to carve these Numbers and patterns on these molds, we have these kinds of common methods.
The first is directly through the engraving machine engraved on the mold. This is usually used when the font or pattern is large. Usually the resulting font has a knife cut on the surface and needs to be polished.
In the normal small – and medium-sized mold, […]

What information should be provided to the manufacturer for the injection molding process？

Many customers need injection molding after a product is newly designed. When a new product needs tool making, what information should the customer provide to the manufacturer?
 
JasonMould shares you a general idea of what is required for tool making and injection molding.
 

3D CAD file of product.
Bill of material ( including materials required for products and surface finishing requirements etc.)
Batch quantity.

With the above information then we can offer you an accurate price.

What Are The Two Part Of a Plastic Injection Mold?

Injection molding is a processing method used in mass production of complex parts. Specific principle refers to: heat melting plastic raw materials by injection molding machine screw into the mold cavity, after cooling and curing, plastic forming products.
 
The plastic mold consists of two parts: moving mold and fixed mold. The moving mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During […]

Why Do Injection Moulds Need To Be Tested?

Defects in most injection molding products are caused during the plasticizing and injection phases of the injection molding parts, but are sometimes related to design irrationality, including the type of injection port, the number of mold cavities, location and size, the design of the cold and hot runner system, and the structure of the product itself. Therefore, in order to avoid product defects caused by mold design, we need to analyze the injection mold during production.
 
After the test results […]

Design Of Ultrasonic Line

Ultrasonic welding in the assembly of plastic parts is commonly used to a process. ABS, PC+ABS, PP, PC, etc. these materials are suitable for ultrasonic welding. Generally used for ultrasonic two parts are required to be the same material. Ultrasonic bonding will be better. If nylon or POM is used to ultrasonic with ABS, this is not feasible.
 
Ultrasonic welding has a lot of advantages, the most critical is to meet the waterproof requirements of the product, the second ultrasonic […]

SPI Mold Standard–Wall Thickness Design

Product structure is undoubtedly the key factor to determine the price of the mold, the realization of a product function has a variety of different design, different design determines the mold manufacturing method is not the same, determine the price of the mold will be different, some structure only need us to pay attention to some design principles, may be able to save a lot of cost.
 
If we ignore the wall thickness of the product, the appearance problems will […]
