Consider a plastic injection molding company with professional sales and engineering teams that you can easily get in touch with.
* How long have you been in business? – Choose a company that has been tooling and molding for more than a decade. That way, you can trust their experience and flexibility in handling a wide array of projects for different kinds of clients. If they are expanding, find out when they started. Some of the best plastic injection molding companies have been expanding their business for over five years, and this enabled them to provide their services to more businesses around the world.
* What is your production capability? – Learn about their machines and production capabilities to determine if they can cater efficiently to your requirements. Larger and modern plastic injection molding machines can produce a lot of products faster. One of the leading service providers in China has built more than 4,000 sets of moldings for different industries.
* Who have you worked for in the past? – Leading plastic injection molding companies have a string of well-known clients, like Canon, Toyota, Brother, Huawei, P&G, and Volkswagen. Remember to ask for references and check with those previous clients to find out if they were satisfied overall with the service and quality of work.
* What kinds of plastics do you use? – Many different kinds of plastics are used in manufacturing, so there should be a specific type of plastic for a particular application. For instance, some plastics are designed for chemical containers, while others are food grade and safe for food preparation and storage. Hence, be sure to ask the types of plastic the prospective plastic injection molding company will use for your product. Verify that it is safe and practical for your intended application.

The Don Valley Brick Performs have been designed in 1889 by the Taylor brothers. John Taylor and his brothers, William and George, had bought the site in the Don Valley in the 1830s where they established a paper mill. While digging post holes to make a fence, William came across some excellent top quality clay. He took a sample to a nearby brick performs where it was confirmed that it would make a high top quality brick. A quarry was soon established at the north end of the site and a brick creating plant was built at the south finish of the home close to the Don River.
The Don Valley Pressed Brick Company made bricks using 3 techniques. The initial was called a soft-mud approach. Clay quarried from the site was mixed with water from nearby Mud Creek, placed in moulds which were dried and then baked in kilns. A second approach named dry-press bricks utilized quarried shale. The shale was placed into moulds and machine pressed. A third process called stiff-mud employed a mixture of clay and shale that utilised less water than the soft-mud procedure. A column of clay was forced by means of a die which was then cut to kind utilizing a wire. Completed product was shipped by cart out of the valley along Pottery Road or by rail on a spur constructed into the yard. Bricks were used largely in Toronto but had been used across the continent. The bricks created were of such very good quality that they won prizes at the Chicago World’s Fair in 1893 and the Toronto Industrial Fair in 1894.
In 1893, the organization added a continuous down-draft kiln which enhanced the good quality and amount of bricks produced. By 1907 the business had two of these kilns in operation and was producing in between 85,000 to one hundred,000 bricks per day.
