As an expert in the field of injection molding for more than 30 years, Ewell Plastics has extensive experience and engineering expertise based on in your industry, we can provide you with plastic injection molding advice.
Injection molding is a manufacturing process that produces parts by injecting molten plastic into a mold.
Multiple materials can be used for injection molding, the most common being thermoplastic polymers.
The plastic is fed into the heating material pipe, mixed with a screw, and then injected into the mold cavity, cooled and solidified in the mold cavity.
The parts to be injection molded must be designed very carefully to facilitate the molding process;Must consider the material used for the part, the required shape and characteristics,The steel selection of the mold and the performance of the molding machine equipment.
Design considerations and possibilities have promoted a wide range of applications in the injection molding process.
Ewell Plastics uses Siemens UG NX 3D CAD software and many years of professional manufacturing experience technology,Provide customers with modulus design services, confirm their needs with customers,Design molds and build prototypes, test the design before the formal mold opening.
Through the initial implementation of a good mold design process, the risk of bad results in the production process can be reduced.
Continuous manufacturing costs can also be reduced and improved,Ewell Plastics has rich professional design and manufacturing experiences, and can provide the best choice according to market demand.
Designers and molders use “Mold Flow Analysis" to see how polymer flow works during the molding process.
We use professional software to replicate the injection molding process.
Any possible weaknesses in the proposed design can be identified beforehand. It can analyze the bonding line and the position of the wind, cooling precautions, and the warpage of the finished product, and other possible problems can be found and eliminated in advance.
Most industries apply mold flow analysis,Including industrial and consumer electronics industries, biotechnology, hospital equipment, automobile and motorcycle industries, food containers, cosmetic packaging containers, etc.
