Natural Materials
Recently.it.has.become.possible.to.use.natural.materials.in.the.molding.pro-
cess..Through.the.use.of.real.sands.and.stone.chip,.sandstone.composite.can.
be.created,.which.is.80.percent.natural.nonprocessed.material.

Products
Designers.can.select.the.best.material.for.their.application,.including.mate-
rials. that. meet. U.S.. Food. and. Drug. Administration. (FDA). requirements..
Additives.for.weather.resistance,.lame.retardation,.or.static.elimination.can.
be. incorporated.. Inserts,. threads,. handles,. minor. undercuts,. lat. surfaces.
without.draft.angles,.or.ine.surface.detail.can.be.part.of.the.design.
Designs.can.also.be.multiwall,.either.hollow.or.foam.illed..Products.that.
can. be. manufactured. using. rotational. molding. include. storage. tanks,. bins.
and. refuse. containers,. airplane. parts,. doll. parts,. road. cones,. footballs,. hel-
mets,. rowing. boats,. and. kayak. hulls.. Playground. slides. and. roofs. are. also.
generally.rotomolded..Nacelle.shell.can.be.produced.by.prepreg.iberglass,.
using.a.rotation.molding.process..We.can.use.injection.molding,.employing.
reinforced. liquid. polymers.. There. is. a. method. of. making. a. wind. turbine.
blade.by.rotate.molds.

Product Design
There.are.many.considerations.for.a.designer.when.designing.a.part..Which.
factors. are. most. important. to. a. client?. For. instance,. a. part. may. need. to. be.
cheap. and. a. certain. color.. However,. if. another. color. is. cheaper,. would. the.
client.be.willing.to.change.colors?.Designers.are.responsible.for.considering.
all.the.limitations.and.beneits.of.using.certain.plastics..This.may.result.in.a.
new.process.being.decided.upon.
