Making plastic parts


Making plastic parts

There are lots of solution to make plastic parts as following:

Prototype making process to make plastic parts, there are plastic molding,  CNC machining, plastic casting, SLA  and SLS process

To use plastic injeciton molding process to make plastic parts, before plastic molding you should make plastic molds.

Also there are thermoforming and blow molding process etc to make plastic parts.  Based on your plastic parts structure, needed quantities, function of plastic parts and plastic parts material, you can choose the most reasonable and reliable psolution. Sure we can handle this job. More information about us, please kindly review Seasky Tooling Group Profile.

PBT molding


PBT

Generic Class

PBT (Polybutylene Terephthalates)

Typical Applications

Household appliances (food processor blades, vacuum cleaner parts, fans, hair dryer housings, coffee makers, etc.), electronics (switches, motor housings, fuse cases, key caps for computer keyboards, connectors, fiber optic buffer tubing, etc.), automotive (grilles, body panels, wheel covers, and components for doors and windows, etc.)

PBT Injection Molding Processing Conditions 

PBT Drying

This material is sensitive to hydrolysis at high temperatures. It is therefore important to dry the material prior to molding. Suggested drying conditions (in air) are 120 C (248 F) for 6 – 8 hours (or 150 C (300 F) for 2 – 4 hours). Moisture levels must be below 0.03%. When using a desiccant dryer, drying at 120 C (248 F) for 2.5 hours is recommended.

PBT Melt Temperature

220 – 280 C (428 – 536 F); aim: 250 C (482 F)

PBT Injection Mold Temperature

40 – 60 C (104 – 140 F) for unreinforced grades. For other grades, a wide range of temperatures can be used, depending on the grade (15 – 80 C / 59 – 176 F). Cooling channels should be properly designed to minimize part warpage. The heat removal must be fast and uniform. Cooling channels of 12 mm diameter are recommended.

PBT Resin Injection Pressure

Moderate (up to maximum of 1500 bar / 21750 psi).

PBT Injection Speed

Fastest possible speeds should be used (due to fast solidification of PBTs)

PBT Molding Runners and Gates

Full round runners are recommended to impart maximum pressure transmission (rule of thumb: runner diameter = part thickness + 1.5 mm). A wide variety of gates may be used. Hot runners may also be used, taking care to avoid drool and material degradation. Gate diameters or depths should preferably be between 0.8 – 1.0 times the part thickness. When using submarine gates, the minimum recommended diameter is 0.75 mm.

PBT Chemical and Physical Properties

PBT is one of the toughest engineering thermoplastics. It is a semicrystalline resin and has excellent chemical resistance, mechanical strength, electrical properties (high dielectric strength and insulation resistance), and heat resistance, all of which are stable over a broad range of environmental conditions. It has very low moisture absorption.

PBT, which is a polyester, is produced by the polycondensation reaction of dimethyl terephthalate an butanediol.

Tensile strength ranges from 50 MPa (7,250 psi) for unfilled grades to 170 MPa (24,650 psi) for glass reinforced grades. High levels of glass fillers make the material more brittle. Crystallization is rapid and this could cause warpage due to non-uniform cooling. In the case of glass filled grades, shrinkage is reduced in the flow direction, but in the cross-flow direction it may be equal to that of the base resin. Shrinkage is of the order of 0.015 – 0.028 mm/mm (1.5 -2.8%). A 30% glass-filled resin has a shrinkage range of 0.3 – 1.6%. The melting point (approximately 225 C / 437 F) and heat distortion temperatures are lower than that of PET. The Vicat softening point is approximately 170 C (338 F). The glass transition temperature ranges from 22 – 43 C (71 – 109 F).

The melt viscosity is fairly low and due to fast crystallization rates, cycle times are typically low.

PBT Major Manufacturers

BASF (Ultradur), Ticona (Celanex), GE Plastics (Lomod, Valox), Bayer (Pocan), Huls (Vestoduv), Mitsubishi Engineering Plastics (Novadur), Teijin Chemicals.

SLA prototype


SLA prototype

SLA rapid prototyping is a discrete layered, layer by layer stacking technology, the direct use of three-dimensional computer data is implemented as a prototype of the product, the more mature laser technology both SLA and SLS rapid prototyping, which the SLA the main material for the photosensitive resin.
 

SLA’s advantages:


A smooth surface, and good quality.
Forming high precision, and accuracy of 0.1mm;
Can be made very fine details and molding of thin-walled structures, high precision, easy post-processing.
 Processing cycle is short, usually it is three days.

The disadvantage of SLA:


1 selectable types of materials is limited, and must be a photosensitive resin.
2 processing strength of the material is a bit weak, can not be repeated disassembly and hit the screw.

CNC Prototype manufacturing

CNC Prototype Manufacturing
CNC Prototype manufacturing,by means of data processing method,use raw materials to process the needed sample.The speed of CNC Processing is quick and the surface of the sample is good,after finishing surfact paiting,screen printing,plating,it looks even more shining than the product produced by molding.CNC technology applicable to a wide range of materials,such as ABS,POM,PC,PA,sample processed from metal,can meet different clients'requirements.Especially those samples processed from engieneering materials with high quality and good density,are characterisc of unparalleled strength and tenacity.CNC Prototype will become the main streem of rapid shaping manufacturing.
  The antetype of CNC Machining Equipment produces the needed products directly by processing such materal as ABS,PMMA,nylon , programming and splitting the three-dimensional data,which can realise the functional feature directly,especially for manufacturing big products.Its use is very extensive.
 
  The choice of material processed by CNC Machine is wide,such as ABS,PC,PMMA,PP,PA,POM,PVC,Aluminum (AL),Copper (AU),Iron (FE) and so on.
  The surface can be dealt with injection, sand blasting, plating, laser carving, drawing, over UV, screen printing, pad printing, hot stamping and so on.

ABS Plastic Molding

ABS Plastic Molding

Generic Class

ABS (Acrylonitrile-Butadiene-Styrene)

Typical Applications For ABS Plastic molding

Automotive (instrument and interior trim panels, glove compartment doors, wheel covers, mirror housings, etc.), refrigerators, small appliance housings and power tools applications (hair dryers, blenders, food processors, lawnmowers, instrument, electronic plastic tool etc.), telephone housings, typewriter housings, typewriter keys, and recreational vehicles such as golf carts and jet skis.

Injection Molding Processing Conditions

ABS Plastic molding DryingABS resins are hygroscopic and drying is required prior to processing. Suggested drying conditions are 80 - 90 C (176 - 195 F) for a minimum of 2 hours. Resin moisture content should be less than 0.1% 
Melt Temperature 200 - 280 C (392 - 536 F); Aim: 230 C (446 F) 
Mold Temperature25 - 80 C (77 - 176 F). (Mold temperatures control the gloss properties; lower mold temperatures produce lower gloss levels) 
Resin Injection Pressure500 - 1,000 bar (7,250 - 14,500 psi) 
Injection SpeedModerate - high 

Chemical and Physical Properties for ABS Plastic Molding

ABS is produced by a combination of three monomers: acrylonitrile, butadiene, and styrene. Each of the monomers impart different properties: hardness, chemical and heat resistance from acrylonitrile; processibility, gloss, and strength from styrene; and toughness and impact resistance from butadiene. Morphologically, ABS is an amorphous resin.
The polymerization of the three monomers produces a terpolymer which has two phases: a continuous phase of styrene-acrylonitrile (SAN) and a dispersed phase of polybutadiene rubber. The properties of ABS are affected by the ratios of the monomers and molecular structure of the two phases. This allows a good deal of flexibility in product design and consequently, there are hundreds of grades available in the market. Commercially available grades offer different characteristics such as medium to high impact, low to high surface gloss, and high heat distortion.
ABS offers superior processibility, appearance, low creep and excellent dimensional stability, and high impact strength.

Major Manufacturers for ABS resin

Dow Chemical (Magnum grades), GE Plastics (Cycolac), Bayer (Lustran), BASF (Terluran), Chi Mei (Polylac), LG Chemical (Lupos), Cheil Synthesis.
