Auto Handle Gas Injection Mold

Product Details

Auto Handle Gas Injection Mold

Gas assisted injection molding, an advanced injection molding technology, directly injects high-pressure nitrogen gas into the plasticized plastic in the mold cavity through the gas assisted controller (segmented pressure control system), so that the plastic part is expanded to create a hollow, but the product surface and appearance are still intact.

How to: Pick a Good Molding Company

Are you a plastic parts buyer? Are you struggling to find a partnership with a valuable molder? We understand identifying a respectable molding company is crucial to your company’s success. It is important to prioritize the process of choosing a good molder. Let’s review a few questions that will assist you in finding a beneficial teammate to support your company’s commitment to quality.

Training and skiil:

Is the new molding house educated on your company’s needs? Are they updated on the processing manuals supplied by the material manufacturer? Your molding company should be aware of the mechanical properties that were advertised and defined in the literature provided by the material manufacturer. Your engineering department believed these mechanical properties to be important, therefore they should be known and implemented. They will ultimately result in the survival of your product in its finished environment.

Does my new molder have the proper knowledge to process the resin of my choice? Do they know how to utilize the best molding practices? Are they aware of resin drying time, heat history, and molding temperatures, etc., etc.? Be sure your new molder is aware of your machine settings. This is crucial in determining a dependable and high quality outcome for your products.

Does the prospective molder have an effective training program for the employees? Are the employees aware of expectations, processes, and deadlines? Communicate your needs with your potential partner.

Does the new molding house know how to handle raw materials; specifically the materials that will develop new products? Knowledge of the materials is essential in the molding technique.

Process:

How about regrind? Does the new molding company know what materials can be reground and blended back into the molding process? Are they aware of the specific ratios of materials? The process by which your molder executes the creation of your products is imperative to dependable results.

Have you evaluated the cleanliness of the new molding house? Are the scrap grinders properly cleaned and prepared to prevent contamination? How should the materials be handled throughout the process in order to achieve goals in the final production (ie: should parts be handled with gloves?). Take a tour of the molding company and evaluate the working conditions.

Relationship

Can you trust your molding house to properly do the job? Do you have an honest and reliable relationship with your new partner? Good communication with your new molder is imperative to satisfying results. Continuous interaction with your new partner and creating a solid foundation of your business relationship will only benefit the development process.

Quality versus Quantity: Is cost the important aspect of your project? Quality stands the test of time; it may not be obvious until parts fail to do their job in the finished product. You supply your customers with reliable products. Be sure your molding company is supplying you with a dependable process.

Think about these questions when choosing your molder. Relay these questions to your potential molding company.

Advantages of gas assisted injection technology:

In recent years, gas assisted injection molding technology has been applied to the production of many plastic products, such as TV or audio housings, automobile plastic products, furniture, kitchen utensils and daily necessities, various types of plastic boxes and toys.

Compared with ordinary injection molding, gas assisted injection molding technology has many incomparable advantages. It can not only reduce the manufacturing cost of plastic products, but also improve some of its properties. Under the condition that the parts can meet the same use requirements, the use of gas assisted injection molding can greatly save plastic materials, and the saving rate can be as high as 50%.

On the one hand, the reduction of the consumption of plastic raw materials will reduce the time of each link of the whole molding cycle; On the other hand, through the introduction of high-pressure gas inside the parts, the shrinkage and deformation of the parts have been greatly improved, so the injection holding time and injection holding pressure can be greatly reduced.

Gas assisted injection molding reduces the working pressure of the injection system and the locking system of the injection machine, correspondingly reduces the energy consumption in production and improves the service life of the injection machine and the mold. At the same time, due to the reduction of the pressure borne by the mold, the manufacturing materials of the mold can be relatively inexpensive. The parts processed by gas assisted technology are hollow structures, which will not only not reduce the mechanical properties of the parts, but also improve them, which is also beneficial to the dimensional stability of the parts.

The process of gas assisted injection is slightly more complicated than that of ordinary injection molding. The control of parts, molds and processes is basically analyzed by computer-aided simulation, while the requirements for the injection molding machine system are relatively simple. More than 80% of the injection molding machines in use can cooperate with the gas assisted injection molding system after simple transformation.

There are no special requirements for raw materials. General thermoplastics and engineering plastics are suitable for gas assisted injection molding. Due to the advantages of gas assisted injection molding technology in many aspects, and its wide range of applications, there are no excessive requirements for equipment and raw materials. Therefore, in the future development, the technology will be more and more widely used in the injection molding industry.

Application of gas assisted injection technology:

Gas assisted injection molding technology can be applied to various plastic products, such as TV sets, refrigerators, air conditioners, or audio enclosures, automobile plastic products, furniture, bathrooms, kitchen appliances, household appliances and daily necessities, various types of plastic boxes, baby product boxes and toys.

Basically, all thermoplastics used for injection molding (reinforced or unreinforced) and general engineering plastics (such as PS, hips, PP, ABS... PES) are applicable to gas assisted injection molding technology.
