Designer Plastics

Design is a matter of balance: weight vs. strength, cost vs. quality, speed vs. accuracy, and so on.  As development progresses, prototyping is an essential part of the balancing process, and prototyping itself presents the designer with choices.

Characteristics of a prototype include quality, cost, and speed.  The required "quality" of a prototype can vary greatly.  In early design stages, the resemblance to a production part can be approximate, but as the process moves toward completion, the prototype must more closely match the finished part.  There are two measures of quality.  The first is form and fit – resemblance in shape, size, finish, and possibly even color to a production part.  The other is function – resemblance in strength, durability, chemical resistance, heat tolerance, and the like.

Polystyrene Sheet

Approx. Price: Rs 350 / KilogramGet Latest Price

Description:

HIPS is a low cost plastic material that is easy to machine and fabricate. It is often specified for low strength structural applications when impact resistance, machinability, and low cost are required. It is frequently used for machining pre-production prototypes since it has excellent dimensional stability and is easy to fabricate, paint and glue. HIPS is used extensively in vacuum forming applications, for products such as point of sale displays and refrigerator linings. The material has high impact resistance and excellent thermo-formability. Typical sheet applications include screen printing, signage, displays.

It offers a consistent, easily printed matte surface for either one or two sided printing applications. It is especially suitable for lithographic or flexographic printing of displays, POP graphics, signs, translights, tags and cards.

 

Applications:

Machined prototypes, low-strength structural components, housings, covers, point of sale, packaging, signs, food packaging – trays, house wares, toys, bathroom cabinets, refrigerator crispers.

P.U. Foam Sheet

Approx. Price: Rs 3,650 / Square FeetGet Latest Price

Description:

Polyurethane Foam is cut and shaped by hand or, particularly the higher densities, by CNC router to produce dimensionally accurate patterns (or bucks) of a composite part. The filled nature of tooling block means that the shaped pattern can already have a high quality surface finish which needs little surface preparation before it can be used to produce a mould.

Lower density P.U. Foams are suitable for hand machining and even hand carving with the higher density model board being suitable only for hand machining or CNC machining. P.U. Model board is also used by architects and architectural model makers to create accurate, stable models of buildings or architectural landscapes. Once a pattern has been cut and finished to the desired shape the P.U. Foam is compatible with a wide range of finishes and release agents.

 

P.U. Foam is available in a comprehensive and standard range of boards for almost every application area in the design, modelling and tooling industries. Its formulation is to keep down weight and density but bring out the special physical values required for the application.

Design Models: Available for making design and styling models these boards are superior in terms of edge stability and surface structure. Furthermore they can be painted without much preparation (little to no filler) and are much more pleasant to machine due to their low dust emission.

Master & Copy Models: Suitable for making master models, it offers as excellent surface finish compared to other similar products. They are especially stable and keep their original form years later due to extensive post-curing process. This offers especially high compressive strength at a comparatively low density.

Fixtures & Gauges: Useful in the automotive industry for gauges and production jigs which render the desired properties concerning thermal expansion, stability and wear resistance for a cost effective solution.

Vac Form Tools: Special care should be given to the surface of vac forming tools to ensure that the part made has a smooth surface. For this reason, it is recommended that all surfaces are sanded down, sealed and, if required, covered with a release agent to ensure a good demould of the vac formed part. Polyurethane Designer boards are especially suitable for small series and prototype quantities.

Foundry Tools: For mid-range and pre-series production quantities cores and core boxes can be milled from polyurethane boards. This saves the traditional step of resin casting. According to empirical research these boards (1000 series) is able to withstand 10,000 shots at around 3 bar pressure.

Sheet Metal Forming Tools: Prototype press tooling, trial press tools, metal bending and hammer forming tools can be made quickly and economically using Polyurethane Designer Boards . Modifying the geometry of the tool is easily possible by cutting out the part of the tool to be changed, gluing in an insert and re-milling the contour. High compressive and flexural strength with good processing properties but also certain elasticity and the ability for the metal sheet to slide over the contours during pressing are important factors for sheet metal forming.
