Materials

Acetals: Delrin® – Celcon®
Acetals are available as a homopolymer (Delrin by Du Pont) or a co-polymer (Celcon by Celanese). Both materials offer excellent machining properties and are ideal for holding close tolerances. The high compression strength and stiffness of acetal make it a good material for high-load applications. Acetal is also available with additives such as moly dry lubricants and Teflon® fibers. These reduce friction and aid machinability.

Nylons
Nylon is available in several compounds and co-polymers. The most commonly used nylons for industrial components are Type 6 (cast) and Type 6/6 (extruded). Both materials exhibit excellent wear resistance and tensile strength, with Type 6 offering slightly better mechanical properties. Nylon generally absorbs more moisture than other bearing materials and therefore may be dimensionally unstable in wet applications requiring close tolerances. Nylon is available in oil or molybdenum disulphide filled compounds which offer a lower coefficient of friction for bearings and wear parts.

PTFE: Teflon®
Polytetrafluoroethylene (PTFE) provides exceptional chemical, electrical, mechanical and thermal properties for many applications. The most recognized source of PTFE resin is Teflon manufactured by Du Pont. PTFE is capable of operating at temperatures up to 550ºF, making it a versatile high-temperature material. Glass fibers are often added to improve the dimensional stability of PTFE under load.

UHMW-PE: Duro-Glide®
UItra-high molecular weight polyethylene (UHMW-PE) has the highest impact and abrasion resistance of any thermoplastic. These properties and its reasonable cost make UHMW a versatile material for many applications where abrasion, impact, or chemical resistance is desired. The low coefficient of friction and high-slip properties of UHMW make it ideal as a wear liner for handling bulk commodities. UHMW can operate successfully at temperatures as low as – 375ºF, making it excellent for cryogenic applications.

Duro Lube
Oil-filled UHMW polyethylene is ideally suited for applications such as wear strips, slider plates and some bearing surfaces where lubrication is desirable to lower the coefficient of friction. All additives in Duro-Glide (white) and Duro-Lube meet FDA requirements for direct food contact.

MOULDS AND MATERIALS

A major advantage of rotamoulding is the low tooling cost compare to plastic injection mold, and die casting, is you are looking for China Plastic Mold Company, you can contact us.

Since the heating and fusing of resin inside a slowly rotating closed mould does not require high pressure, moulds, therefore, need not be as costly or complex as those tooled for other processes. Depending on requirements, moulds can be made from several materials:

Cast aluminium alloy: the popular choice, with good heat transfer and excellent mould definition. It is best for small to medium sized mouldings.

Sheet mild steel: for fabricating moulds for large mouldings.

Cast beryllium copper: for quality moulds producing very detailed surface finishes.

Electroformed copper nickel: suitable for undercuts and the highest surface reproduction and finish.

90% of rotational mouldings are made of polyethylene (PE), a polymer with immense versatility ranging from food grade to vandal-resistant and flame retardant grades for handling waste materials, fuels and corrosive substances.

Cross-linkable PE has been developed with superior resistance to chemicals and environmental stress cracking suitable for the production of canoes, chemical plant and high performance containers.

In addition to polyvinyl chloride, EVA, polyester elastomers and certain rubbers for moulding flexible and inflatable products, engineering polymers have also been developed including polypropylene, nylon, polycarbonate, and polyurethane.

Some thermosets have been introduced too. However, the flow characteristics of the resin are all important for successful processing, hence the ubiquity of polyethylene. if plastic molding parts made in polyethylene, it is PP injection molding, need this service? Contact us.

These materials and technological advances, combined with well designed surface finishes and graphics, are leading to the rotamoulding process away from traditional solutions into new areas of product application.

Plastic Mold Company

We are a plastic mold company, provide plastic molds and moding service.

the last year, An important customer came to ST Tooling from US, CA, requiring a new servcie palstic mold and plastic molding company.Driver’s Side Airbag Cover in critically short time. Initial parts from productive materials were required in only 4 weeks. Several rapid tooling processes were considered for this project. The PolySteel™ process was selected for the following reason:

  • Tool accuracy
  • Lowest cost
  • Fastest timing
  • Robust process

PolySteel™ is a new polymeric tooling process developed by ST Tooling of Fresno, CA. Tools are created directly from rapid prototype or other patterns. The material is highly loaded with steel (greater than 90% by weight). A very high degree of accuracy is maintained from the pattern due to negligible process shrinkage (.0002 in./in.). The resulting tools have exceptional strength and durability for injection molding applications. 

This major Original Equipment Manufacturer (OEM) had confidence the PolySteel™ process would work for this Airbag Cover project since PolySteel™ had already been proven successful with more abrasive materials requiring higher molding temperatures and pressures (such as ABS and Nylon 40% glass filled). 

Plastic Mold
Plastic Mold



The 12.5″ x 12.5″ x 6 Airbag Cover mold (317mm x 152mm) would normally require 8 separate components, 4 of which are slides. Due to the versatile nature of the PolySteel™ process the tool was produced with a 1-piece stripper plate, 2 core sections and 1 cavity, completely eliminating the need for slides, thus reducing total components by 50%. 

The part used to create the Airbag Cover mold was a stereolithography (SL) pattern. Since time was of the essence, the OEM’s in-house service bureau built the pattern over a weekend. Leather grain texture was applied to the exposed surface of the pattern using a special 2-day process. This greatly reduced the typical lead time required for conventional graining procedures. The PolySteel™ material was molded directly over the pattern without the need for machined inserts. The tool was constructed in a simple welded frame, which replaced the conventional mold base. Holes for the ejection system were molded in place. The characteristics of PolySteel™ made it possible to meet the demanding requirements of the Airbag Cover mold without the need for water cooling lines. Since the PolySteel™ process replicated the grain on the pattern, the parts produced from production intent materials were able to be used for show as well as deployment testing.

More than 100 Airbags Covers were molded in the PolySteel™ tool to meet initial requirements. Over the following month, the mold was used for parametric studies by revising the tear seam and changing the emblem embossment area. Modifications of this nature are accomplished quickly and easily in PolySteel™ tools. An additional 225 parts were then produced from three (3) alternate productive materials. 

Even with the premium paid for expedited delivery, the PolySteel™ tooling process still saved the OEM 12% in tool costs and even more significantly 80% in typical timing. This tooling technology played a key role enabling delivery of a new Driver’s Side Airbag Cover in a timely manner for a very important customer.

Mechanical Properties of Malleable Iron

The different grades of malleable iron are essentially the result of different heat treatments. Just as a medium carbon steel can be heat treated to a wide range in properties so can malleable iron, but malleable is even more versatile. The combined carbon content, on which heat treatment depends, can be adjusted from none, as when the microstructure is entirely ferritic, to that of a fully pearlitic structure. Read more

Mechanical Properties of Cast Carbon and Low Alloy Steels

For the purpose of this article, carbon steels are considered to be those steels in which carbon is the principal alloying element. Other elements that are present and that, in general, are required to be reported are manganese, silicon, phosphorous and sulfur. In a sense, all of these elements are residuals from the raw materials used in the manufacture of the steel, although the addition of manganese is often made during the steel making process to counter the deleterious effect of sulfur and silicon is added to aid in deoxidation.
