Plastic Injection Molding Company in Plastic Industry | PTMS

China is the largest manufacturing country in the world, because there are many different plastic products manufacturers in China and the products were exported to the different worldwide countries. Why China can produce many products? Many reasons for this issue, we collected some useful information as below: Reform and opening-up in 1978. The government make reform and opening-up decision at that time, some organizations changed into others and some are cancelled. Many people can do something if they have the ability, for example, business, factory, shop and other jobs. Many foreign companies come the country and invest companies to make mass production, many Chinese people can work in the different companies, so, the economic become better and better, the people’s life goes well since 1978. Coastal economy. Chinese economy is not good and rather poor at that time, so the government want to development the coastal area at the first beginning, because the delivery cost is very cheaper...

Low volume plastic injection molding become popular in the recently years, we will discuss the situation and share the reason as following. Economy. As we knew, the global economy become bad since 2008, it makes many different industries develop slowly year by year, so the requirement is not big. Many products are made by some different plastic parts, and the parts is made by injection, so the products just need low volume production. Product upgrading. The company always upgrade the products to get more profits, people don’t like the complex design products, they like simple products, so the parts will be less and less in such situation. So, low volume injection molding is the best choice for the products. Market competition. The company can’t make big production for some products, because there are many different companies in the markets, they also produce the similar products, it will be much difficult to sell all the products, in such case, low volume is the best choice for the mar...

When it comes to manufacturing products and parts, plastic injection molding is usually one of the top choices. This is due to a number of reasons, including better efficiency, lower cost, and increased durability. If you want to choose the right injection molding company, ask them the following questions: Is your company ISO 9001 certified? An ISO 9001 certified company can provide high-quality plastic components. PTMS is an ISO9001-2008 company, meaning they comply with the quality standards set by ISO. Does your company provide prototyping services? Since prototypes help show customers what their plastic injection molded part will look like, they’re an important part of the plastic injection molding process. Companies like PTMS provide prototyping services for businesses like yours to ensure your custom plastic parts are made to your exact specifications. Does your company have engineers with proper education and training? The industry of plastic injection molding presents new t...

In today’s manufacturing industry, injection molding versus 3D printing represents a classic debate of ‘old’ versus ‘new.’ Here, our custom injection molding expert determine whether or not 3D printing is cheaper than injection molding. Overall quality While comparing at a mass scale is one thing, what happens when parts are compared individually? Yes, 3D printed parts are functional, but their injection-molded counterparts are better. This is mainly because the injection molding process produces a singular unit in one shot of material, curing to produce a solid piece. 3D printing is additive manufacturing . This means they’re built up in iterative pieces of material, increasing the likelihood for issues to be introduced throughout the part’s printing process. In contrast, injection molded parts are produced in bulk at industry-grade compliance standards directly from the mold. Simply put, 3D printing makes sense for very quick turnaround projects, short-run projects of around 10 ...

With plastic i njection molding , it’s possible to produce many parts with quick cycle times and great accuracy. Generally, the injection molding process includes heating, melting, and injecting a certain amount of polymer materials into a mold under high pressure. Following are the main units of an injection molding machine: Feed hopper Heated barrel Injection unit (or crew) Clamp unit, which holds the mold together Ejection unit, which removes the part from the mold Benefits Injection molding provides a plethora of benefits, including: Cost savings Automated plastic injection molding too ls augment the efficient, already fast process of manufacturing quality parts. Compared to the traditional manufacturing process, injection molding produces less waste. Flexible choice of color and material To produce the right effect and properties for your particular product, you can choose from a number of color blend choices and coloring systems. Strength The proper balance of material and desi...

Plastic injection molding is one of the best methods for manufacturing parts. The benefits include operation automation, size and shape flexibility, fast production speed, and high efficiency. In addition, products from injection molding are usually precise in size. However, a number of injection molding defects continue to pose a threat to the products’ quality. Here, we discuss some injection molding parts defects and what can be done to avoid them. Warping Warping is a molding defect that appears when different components of the plastic part unevenly shrink. During the cooling phase of the molding process, uneven shrinkage may put stress on parts causing twisting or bending. Usually, the cause of warpage is the cooling process that happens rapidly. How to avoid it? By lowering the temperature of the plastic material or mold and by ensuring the cooling process is lengthy enough to prevent uneven stresses, it’s possible to prevent warping. Burns During injection, the overheated re...

Although the automotive industry has traditionally been associated with steel and metal, plastic has become very important in the manufacturing of automobiles. This is because plastics are sturdier and, in some cases, durable than their metal counterparts. In fact, parts manufactured using automotive injection molding usually meet certain expectations more effectively than metal parts could. Here, we go through some of the applications of plastic injection molding in the automotive industry. Protection cases of electrical components Vehicles have a number of electrical components, and they must be safeguarded from heat, water, as well as other external factors. Thanks to injection molding techniques, building protection cases using thermoplastics isn’t an issue. These cases are used as an external covering for sensors and electrical machinery present in the automobile. Plastic provides immunity to any sort of physical damage (such as sudden shock) to the components. Exterior comp...

It requires a special skillset to design plastic injection molded products. You should be familiar with the plastic injection molding process, understand how the plastic injection molding machine works , and how the material behaves. Even if you’re not an expert in plastic injection molding, here are 3 things to keep in mind when designing your first plastic part. 1. Uniform wall thickness You should aim to make the wall thickness of your part as consistent as possible. While it’s okay if you don’t have uniform wall thickness to some degree, uneven wall thickness considerably increases the probability of material flow restrictions, longer cooling times, molded-in stress, voids, warpage, and sink marks . If you have an uneven wall thickness, it’s best to have slick transitions that taper over a certain distance. The capability of the material to fill and the part’s size will decide the minimum wall thickness for your plastic injected part. 2. If possible, avoid undercuts While undercuts...
