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 […]

Key Points Of Boss Design

Screw post is also called boss, which is a feature of most products. What key points should we pay attention to when designing the structure? Let’s have a look:
 

The wall thickness of the boss, at the time of structure design, we need to consider the strength of the boss, so as far as possible the post do thick wall thickness, but this will lead to positive forming parts shrink, we can design according to the main body of the […]

The reason bubble caused in plastic product of injection molding

How should plastic product appear bubble to do? Our engineer’s answer is that the reason may in the equipment, plastic mold, and may also in the injection process, the following is the reason analysis of the process, hope to help you solve the problem.
 

The back pressure of screw pre-molding is too low and the rotation speed is too high, which causes the screw to return too fast, and the air is easily pushed to the front end of the […]

Analysis And Solution Of Cracking In Injection Molding

Cracks, including filament cracks, microcrack, whitening, cracking on the surface of parts, as well as cracks and fracture time due to component adhesion, flow path adhesion or traumatic damage. The main reasons are as follows:
 

Processing:

 
(1) Excessive processing pressure, too fast, the more filling materials, injection, holding pressure for too long, will cause excessive internal stress and cracking.
 
(2) Adjust the speed and pressure of mold opening to prevent the quick and strong drawing parts from causing demoulding cracking.
 
(3) Adjust the […]

Classification of injection mold

All kinds of tools used in our daily production and life, from the body shell to the head screw, button and the shell of all kinds of household appliances, have an inseparable relationship with the mold. The shape of the mold determines the shape of these products. The processing accuracy and quality of the mould also affect the quality of the product. According to the different materials of the product, the mould can be divided into injection mould, forging […]
