plastic mould and custom injection moulding tips

China Injection Molding In the machine industry, there are many people who are aware that  Plastic Injection Molding  is just as necessary and important as any other machining process. Plastic injection molding equipment should be purchased after considering the following factors: shot volume, tie bar distance, ejector travel, platen dimensions, and tonnage. Shot Volume An injection molding machine’s shot size refers to how much plastic it can inject into a mold cavity during a single molding cycle. In the U.S., the amount of “general purpose polystyrene” (GPPS) is measured in ounces, while in Europe and Asia it is measured in cm3. It is a good idea to always search for a machine that can produce 30-40% more shots than the size of your parts. Platen Dimensions Platens are the tools that hold the  cavity of the mold . Platens are inserted and clamped securely to the mold, which is spaced apart. During the molding process, the two platens are brought together and held under tonnag...

[caption id="attachment_4753" align="aligncenter" width="1024"] injection molding cycle[/caption] An injection molding operation is a process by which plastic materials molten in a mold are injected, and then cooled down, in order to achieve molded products. Methods such as this are suitable for mass-producing products with complex shapes, and play a major role in the sector of plastic processing. A mold must be properly mounted and started up for production after it has been installed. This procedure will ensure that the mold is mounted correctly and protected properly.Choosing the right machine for your mold installation will depend on its size. The status of each machine should be ascertained after selecting one. The following items should be examined: Ensure that hydraulic oil is at the proper level. Heater bands have been installed and are functioning. Mold temperature controllers can be controlled. There is no oil in the i...

Why China injection molding-Topworks? Injection molding overseas is not cost-effective for most companies. The high shipping costs and delivery delays by overseas customs would make it inefficient, so make it locally? You have likely heard negatively about the quality of plastic injection molding companies in China . However, the plastic mold outsourcing industry within China has grown consistently. Many companies worldwide continue to purchase China plastic injection molding or China injection molding services; some are placing large orders, and some even set up their own sourcing office in China. People prefer advanced mold injection technology and durable injection parts. The Chinese mold supplier is a reliable business partner in the injection mold industry. As a Chinese custom-made plastic mold manufacturer, Topworks takes pride in offering our customers the best quality in plastic molds made using advanced tech. With over a decade of experience, Topworks take on e...

[toc] For a design to be successful , all the necessary information must be available before beginning. If this simple rule is ignored, many bad things can happen, such as poor designs, misunderstandings, poor component quality, and disputes between suppliers and end users. Experienced designers will almost certainly follow all the steps to avoid pitfalls, but even then, they may run into obstacles from time to time due to the sheer number of potential pitfalls. As a result, it is advantageous to have a checklist that can be added to at any time and can be checked off point-by-point to ensure that nothing is missed. Creating a Checklist Before Design: Original estimate details Diagrams of components Component dimensions Material for the component Amount necessary Purpose of components Product tolerances Impression count Gating Ejection Appearance of component parts Guide to Designing Moulds Original Estimat...

How Products Are Developed A key component of product development is mold design. The relationship between product and mold design is such that both product and mold design engineers will benefit from knowledge of the design and production of plastics parts and molds. In Figure below  you will see the steps involved in the typical product development process, which includes concept development, product design, business planning, and launch. While the process itself varies, the two characteristics that are common to most are: In order to ensure the design and manufacturing process are complete and on track, a development plan is necessary. Using the toll-gate method, a larger budget is approved only after significant reviews are conducted towards project progress.  Following is a description of each stage. Determination of the product Analyzing the market, benchmarking competitors, defining product specifications, and assessing profitabilit...

plastic mold design Designers need to gather all information before they start designing a mold. - Do you have a product design that is ready to go? Having information missing or making changes to the mold after beginning can cause frustration, and it wastes valuable time. - How do the tolerances look? In the first estimate of the mold cost and the first bid for the mold price, were the dimensions on the drawing the same as what was specified in the estimate? If there were no tolerances specified in the quote, this can be especially problematic; for example, if a molder asks for an estimate of the mold cost so he knows how much the customer's product costs . Sadly, there are often no drawings, just samples or models of the product used as the basis for the estimate. Designing a product with mold designers in mind will ensure that the finished product is easy to mold and satisfies the intended use, but if they do that, they should not make a product drawing, or they shoul...
