He and the CEO of Bodacious Case watched as the ton press molded molten polymer into one of the precision parts for our clients IPhone case.
The camera man shot high definition video of the press from several angles sure to get the opening of the still hot mold and release of the cooling part, the star of the interview.
The plant with rows of machines in varying sizes was the site for the latest Made in America interview aired Wednesday and Thursday December 5th and 6th. Our machines run so smoothly and quietly that the interview was held on the plant floor during a typical production run on numerous machines.
At normal conversation levels the interview took place right next to a running ton press that was actively molding the Bodacious cases. The innovative IPhone case is made of three parts that are configured into 3 styles with multiple colors. The case can be configured with or without port covers and with or without the credit card holder.
The front accepts a polycarbonate protective cover for the screen made by Engineering materials week 7 Industries. Each component is made to precisely fit together allowing users to exchange bands as well as fronts and backs.
As with all of our customers we stand ready to provide the support they need from the initial engineer of parts and molds to the efficient production of quality parts delivered in a timely and cost effective manner. We even welcome the television shows that may be running a feature on your great product, made in America.
A quality plastic engineering and molding company, Precise Mold and Engineering specializes in not just injection molding, as is needed with our latest client, but in: Bodacious cases needed hinges on several ports opening on the case.
Hinges require mold designs that allow thin flexible bridges to form between to components of the final product. Too much polymer across this bridge makes the hinge stiff and unworkable.
Too little polymer leaves a thin and often brittle hinge. Knowing the polymer and its tolerances is part of the design process. It is a problem for some plastics manufactures.
Not Precise Mold and Engineering, we have years of experience in molding a wide variety of polymers into parts of modest size to some of the smallest parts you will ever see.
The case is made of two polymers each with its own melting point and shrinkage properties. The band a softer polymer has just enough stretch to fit around the sides of the case with the elasticity to hold firmly in place and the flexibility to incorporate hinges for port access.
Designing a case graphically that snaps together is one thing. Designing a mold and cutting into a block of metal to create cavities and channels for polymer to flow must consider not only the size of the cavity needed to hold the volume of material, but also the size of the channels that keep the molten polymer flowing into the cavities.
The design must also consider the slight shrinkage of materials as it cool. Where you aware the polymer shrinks more in one direction than another based on which way the material flows into a cavity?
Improperly designed molds can leave eddies or swirls visible in the surface of a finished part. Air vents to one ten-thousands of an inch must be cut into the mold to allow air to escape the cavity while retaining the polymer.
Mold design also includes the needs of the customer including their need for high volume product or smaller runs with much less expensive molds. High run molds are made of steel where less expensive molds for shorter runs can be made of aluminum.
Some molds can be more cost effectively made if they share a frame seducing the bulk materials total cost of multiple separate molds. Sure production runs will take longer, but we are designing solutions that work best for our clients and those solutions include affordable options. Making a mold is one step in the process, knowing how to use the mold and polymers in these huge presses is an art in itself.
Choosing too large a press means the molten polymer will be delivered too fast. Too high a temperature will burn the plastic. Improper closure can cause excessive flash.
The wrong polymer and the mold may be sent to the shop for extensive cleaning. Simply touching the surface of some cooled molds with the finger can etch a finger print into the polished surface.IES ACADEMY is the one of the premier institute, established in year IES academy is the only institute that produced First All India Rank 1 (IES- , E&T) among all coaching institutes in entire .
LIPAc Operation stopped for yearly maintenance: Since August 13th, the operation has been stopped to allow the yearly maintenance as well as the installation of the HEBT/BD equipment required for the next phase. Tissue engineering is the use of a combination of cells, engineering and materials methods, and suitable biochemical and physicochemical factors to improve or replace biological tissues.
Tissue engineering involves the use of a tissue scaffold for the formation of new viable tissue for a medical purpose. While it was once categorized as .
Learning Materials in a Problem Based Course by James Busfield and Ton Peijs. A booklet in the 12 Guides to Lecturers series published by the UK Centre for Materials Education.
Problem Based Learning (PBL) is a concept used to enhance multidisciplinary skills using planned problem scenarios. It is an active way of learning that teaches students problem solving skills, while at the same time.
Welcome to Aggieland, #TAMU22! Texas A&M Science celebrated #TAMU22 and the start of another fall semester with a Howdy Week event featuring Bahama Buck's snow cones, fellowship and fun in the Menos statue courtyard adjacent to the John R.
Blocker Building. Recent economic and ecological issues have encouraged the development of new materials with less environmental impact, produced from renewable resources with a high level of biodegradability. Therefore, all over the world, there is rising acceptance in materials demonstrating efficient use of renewable resources.
