Injection Molding Process, Basic Step 1: Product Design
Design is one of the most important facets of the production process because it’s the earliest opportunity to prevent expensive mistakes later on. (Of course, determining whether you have a good idea in the first place is also important, but more on that here.) There are many objectives to design for: function, aesthetics, manufacturability, assembly, etc. The right design is one that accomplishes the required objectives to a satisfactory level, but it may take a lot of creativity to get there. Product design is most often accomplished with computer aided design (CAD) software, like SolidWorks. (Click here for nine pro tips on how to best use SolidWorks in design and engineering.) Proficiency with CAD software is vital because it allows for quicker iterations and more accurate prototyping if necessary.

Design and engineering for injection molding
Some specific ways to avoid costly mistakes during the product design process are to plan for uniform wall thickness whenever possible, and to gradually transition from one thickness to another when changes in thickness are not avoidable. It is also important to avoid building stress into the design, such as corners that are 90 degrees or less. (Read more about Injection Molding Defects here.)

Injection Molding Process, Basic Step 2: Mold Design
After a looks-like, feels-like design has been tested and slated for further production, the mold (or die) needs to be designed for injection mold manufacturing. Molds are commonly made from these types of metals:

Hardened steel: Typically the most expensive material to use for a mold, and generally the longest-lasting (which can drive down price per unit). This makes hardened steel a good material choice for products where multiple hundreds of thousands are to be produced.
Prehardened steel: Does not last as many cycles as hardened steel, and is less expensive to create.
Aluminum: Most commonly used for single cavity "Prototype Tooling" when a relatively low number of parts are needed for testing. Once the injection molded parts from this tool are tested and approved, then a multi cavity steel production tool is produced. It is possible to get many thousands of parts from an aluminum tool but typically it is used for lower quantities.
njection Molding Process, Basic Step 3: The Manufacturing Process
When a product has been properly designed, approved, and die cast, it’s time to start the actual manufacturing! Here are the basics of the injection molding proces.

Thermoset or thermoplastic material in granular form is fed through a hopper into a heating barrel. (Learn more about the differences between plastics in our PLASTICS course.) The plastic is heated to a predetermined temperature and driven by a large screw through the gate(s) and into the mold. Once the mold is filled, the screw will remain in place to apply appropriate pressure for the duration of a predetermined cooling time. Upon reaching this point, the screw is withdrawn, the mold opened, and the part ejected. Gates will either shear off automatically or be manually removed. This cycle will repeat over and over, and can be used to create hundreds of thousands of parts in a relatively short amount of time.

   Printed Circuit Board (PCB)
A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. Components (e.g. capacitors, resistors or active devices) are generally soldered on the PCB. Advanced PCBs may contain components embedded in the substrate. PCBs can be single sided (one copper layer), double sided (two copper layers) or multi-layer (outer and inner layers). Conductors on different layers are connected with vias. 

Multi-layer PCBs allow for much higher component density. FR-4 glass epoxy is the primary insulating substrate. A basic building block of the PCB is an FR-4 panel with a thin layer of copper foil laminated to one or both sides. In multi-layer boards multiple layers of material are laminated together. Printed circuit boards are used in all but the simplest electronic products. When the board has no embedded components it is more correctly called a printed wiring board (PWB) or etched wiring board. However, the term printed wiring board has fallen into disuse. A PCB populated with electronic components is called a printed circuit assembly (PCA), printed circuit board assembly or PCB assembly (PCBA). The IPC preferred term for assembled boards is circuit card assembly (CCA), and for assembled backplanes it is backplane assemblies. The term PCB is used informally both for bare and assembled boards.

A board designed in 1967; the sweeping curves in the traces are evidence of freehand design using adhesive tape. Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. Rub-on dry transfers of common component footprints increased efficiency. Traces were made with self-adhesive tape. Pre-printed non-reproducing grids on the mylar assisted in layout. To fabricate the board, the finished photomask was photolithographically reproduced onto a photoresist coating on the blank copper-clad boards.[citation needed]

3D metal printed prototypes
SLA & SLS Rapid Prototypes
SLA & SLS are two of the original 3D printing processes. These methods are ideal for making rapid, one-off prototypes in plastic. These prototypes can be used as-is, or to function as master patterns for polyurethane vacuum casting. Like with other 3D additive manufacturing processes, you can add complex internal features that can’t be made conventionally.

Polyurethane Vacuum Castings
Polyurethane vacuum casting  is a rapid prototyping technique suited for making up to 30 copies of a master pattern from a silicone rubber mold. The level of detail and surface finish of the copies is dependent on the quality of the master pattern. You choose the casting compound to match your design idea – hard or soft, colored or clear. We even offer overmolding to combine two or more different types of material in a single finished casting.

The next two photos are considered reversed polarized (RP-SMA).

We have a team of specialists who are experts at preparing master samples for casting. Samples can be provided by you or we can make them using CNC machining or one of our 3D printing services such as DMLM, SLA or SLS.

Functions and benefits of Insurance


There are some benefits if we follow the insurance program, among which are the following:

1. Tools or Infrastructure to save

Saving infrastructure means that the amount you are insured has cash value and can be taken back, these include certain types of insurance such as whole life or endowment, there kinds of insurance products which are deliberately combined with investments, that is called unitlink.

2. Provide protection or Security.

By having an insurance policy, the insured will be spared from possibleincidence risk losses later in the day and feel safe and calm his soul because the insured object has been dijaminan by the insurer.

3. Assignment of costs and benefits are More Justly.

The greater the risk of losses arising then the greater the premium coverage from the insurer.

4. Provide a level of certainty.

Is the main benefit of insurance because they are basically trying to reduce an uncertain consequences of an adverse circumstance, which has been predicted beforehand so the cost of these losses to be definitely or relatively more for sure.

5. Help improve Productivity for insured Businesses

The insured who would invest in a specific line of business (High Risk Business) when a portion of the investment risk can be covered by insurance to reduce the risk that may occur at a later date.

6. Credit Guarantee

Insurance policies can be used to guarantee loans, usually only to life insurance and very selective to certain types of credit and bank.


The types of Risks that may be Insured

In this life is a risk we cannot avoid, but can be minimised by reducingthe risk or move to another party.

But not all risks can be insured, the risks can be insured should meet the following characteristics:
Losses are definitely (definitive), such as death, sickness, disability, and old age, including conditions that can be identified, such as the building crumbled, tenggelammnya ship, or the fall of airplanes.
Losses occur because of accidental factors, such as the critical final stages of disease, accidents, or natural disasters.
Losses are convincing, as someone who is no longer able to work because of a work accident, the engine doesn't work anymore because of the heavily damaged.
The insured object can be assessed and converted with value for money.
The risks that occur must be natural, happen because of accidental and was not planned in advance.
The risk of that happening don't violate the public interest.
Insurance premiums assessed value is quite reasonable.
The party filing the insurance should have interests that can be insured.
Understanding the internet (interconnection networking) is an open global communications network and connect millions even billions of computer networks of various types and types, by using a type of communication such as the telephone, satellites and others.

The internet is a computer network was originally formed by the United States Department of defence in 1969, through a project called ARPANET.

The initial mission of the project was initially only for military purposesonly, but it gradually continues to grow and can be enjoyed by all walks of life
The creation of the internet has brought a very significant changes in various aspects of human life.

In addition, the internet has also given birth to a new world that has apattern, the pattern of different characteristics at the same time with the real world.
Facilities found on the Internet

The Internet is often referred to as the universe of information servingthe many amenities that can be enjoyed by internet users. Here are some of the facilities that can be enjoyed by internet users, among others:

1. The WWW

The World Wide Web or often abbreviated with the WWW is a system that is found on the internet and is in charge of conducting a search at the same time granting the information quickly by using hypertext technology.

To create hypertext, diciptakanlah a programming language called Hyper Text Markup Language (HTML).

HTML function binds the WWW address or a file in a document which is usually conditioned extention UR*.htm or * .html.

To send the file, takes the role of specific data delivery protocol IE theHyper Text Transfer Protocol (HTTP). In addition, to find any relationship of hypertext required Uniform Resource Locator (URL).

2. Email

Mail or email is electronic messages that are sent and received between users of the computer.

Email allows an individual to send messages to other individuals with a fast time, even in a matter of seconds.

Currently the development of email is very fast, email is not only contain text only. We can attach multimedia files such as pictures, photographs, videos are even animated.

3. Mailing lists

Mailing List or who is often referred to with the mailing list is one of the discussion group on the internet.

To become a member of a mailing list, we first send an email to the address subsription and pending approval from the mailing list moderators. Typically, a member of the mailing list Exchange information, opinionsand more.

4. BBS

Bulletin Board System or commonly abbreviated BBS is an information center that provides a variety of information from a variety of fields such as education, business, social, technology and others.

By using this facility, users can exchange thoughts with other users on a particular topic.

Usually, users who access the BBS can upload as well as download news from other users with ease.

5. Chat

Chat is a conversation between two or more computer users in realtime by utilizing the internet.

For computer users who have been supplementing its computer device with a webcam, they can chat with other users who see the face on the invite chat.
