The automobile industry has developed rapidly in the past ten years, and more and more new products have entered the market, such as new energy vehicles. A large number of automatic parts are made of plastic. As a new material of automobile parts, plastic parts can reduce the weight of automobile and save energy, so they are widely used in automobile industry. This means that a large number of plastic injection molds are needed to produce the required plastic […]
The surface of the plastic part can be sprayed to ensure the brightness of the product. Because plastic is so hard to embody, plastic parts look darker, and even darker if they are covered in leather. Therefore, in the pursuit of a beautiful surface, Some customers requires to spray a layer of painting on the surface of plastic parts. This will ensure the brightness of the product.
Spraying the surface of plastic parts can reduce the scrap rate of parts. […]
As we all know, the stripe defect in mold is a very serious matter, it will directly affect the accuracy of injection molding, and will also lead to product scrap, so we must pay attention to. So, how can we avoid this defect?
Proper design, careful processing, reasonable mold repair and timely nitriding are the key measures to prevent the occurrence of stripe defects in precision injection molding.
It should be processed in strict accordance with the requirements of the drawing, […]
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 […]
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 […]
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 […]
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.
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 […]
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, […]
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.)
With the above information then we can offer you an accurate price.
About JasonMould Industrial Company Limited
Jasonmould is a China mold maker of plastic […]
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 […]
