Every great product starts with great design!  We can get you started with engineering and design, and develop professional drawing and 3D models. We work with very talented designers that will design your product for plastic injection.

This is very important because a basic design might have features that can make tooling more expensive. Our 25 years experience in the molding business will help make your part in the most cost effective manner.

 All decision making takes place on one level. Meaning, the person you are dealing with will have the power to help you make decisions quickly based on a lifetime of experience in the custom injection molding business.

Visualization capabilities are enhanced in the early designing phase with use of rapid prototyping. The user gets a fair idea of how the final product will look by observing the working model in early design stage.

 
The design flaws can be detected before manufacture process is initiated.  


Rapid prototyping enables producer and users to participate actively. Active participation between the users and producer is encouraged.
The user is able to get a higher output.


The development costs are reduced considerably, hence rapid prototyping proves to be quite cost effective.
Rapid prototyping increases the speed of system development.


With rapid prototyping, it is possible to detect deficiencies in the earlier prototype, coding activities and requirement analysis.
Rapid prototyping assists in refining the potential risks that are involved in the delivery


The different aspects of the prototype can be tried and tested and immediate feedback is possible form user.
Better communication is enabled between the users and designer as there is clear expression of requirements and expectations in the start itself.


Rapid prototyping enables easy delivery of high quality product.


Types of rapid prototyping

 

3D printing

Advantages:

     Fast Fabrication

     Low Material Cost

     Variety of Colors

     No external supports are required     

 

Disadvantages:

     Resolution

     Surface Finish

     Part Fragility

     Materials Available

 


Fused Deposit Modeling (FDM)

Advantages:

     Numerous Material Available

     ABS

     Casting waxes

     Nylon like polymers

     PC

     PPS

     Water soluble materials

     Good layer bonding with ABS materials

     Fast small part production

     Good for parts with thin walls

     Usage of water soluble materials allow support structures to be easily removable

 

Disadvantages:

     Slow production rates for thick sectioned parts

     Secondary operations are needed to remove support structures

     Poor surface finishes

 


Inkjet Methods

Advantages:

     Capable of producing fine finishes

     Fast production of parts when using multiple jet heads

 

Disadvantages:

     Long production times for parts with fine finishes

     Less accuracy when using multiple jet heads

     Supports must be removed in secondary operations

     Additional operation needed to provide uniform layer thickness

 



Stereolithography (SLA)

Advantages:

     Good accuracy (approximately + 0.005 inches)

     Superior surface finish

     Able to use a wide range of materials

     Compatible with several color changing materials

     Widely available

 

Disadvantages:

     Liquid materials tend to be messy

     Parts produced may require a post-curing operation in a separate oven

     Few materials compatible

     Warpage and shrinkage issues

     Require supports

 



Selective Laser Sintering (SLS)

Advantages:

     No Supports Required

     No final curing process required

     Can Fabricate metal and ceramic parts



 

Disadvantages:

     Rough Surface Finishing

     Need to infiltrate parts with another material to improve mechanical characteristics

     Is unable to replicate molded parts

     Material changeovers are difficult


We can help you decide what prototype process is right for you depending on your application and needs.
