High Pressure die casting

/in , , , , , , /by

GC High Pressure die casting
The company supplies diecast components up to 2.5kg in weight in zinc and aluminium alloys to a diverse range of markets including defence, aerospace, construction, electrical, marine, and telecommunications industries.

Design
Extensive expertise built up over more than thirty years in continuous production, enables the best possible component design to be provided, using the latest draughting and solid modelling technology. The company is happy to advise on details of component design, including the improvement and rationalisation of existing components.

Tooling
GC High Pressure Die casting also provides a full mould and toolmaking service.

Quality Assurance
From the first design stage, a quality assurance plan is drawn up covering all aspects of the component. This is updated with knowledge gained during the sampling phase and then formalised and issued to ensure that every stage of production is correctly controlled.

Production
The company has a total of 24 hot and cold chamber machines, with capacities up to 350 tonnes closing force.

Finishing
The high quality of castings produced ensures that minimal, if any, finishing is required before components are plated, painted or powder coated.

THE PROCESSES

        GC High Pressure die casting uses two production techniques depending primarily on the metal being cast.

Cold chamber high pressure die casting
Used for aluminium and its alloys which require a melting temperature too high for the hot chamber force pump mechanism to operate. The metal is melted in a totally separate furnace and transferred by ladle into an extension tube (shot sleeve) leading to the mould tool. From here it is forced into the die by a plunger.

Hot chamber high pressure die casting 
Used principally for casting components in zinc alloys with comparatively low melting points. The metal is melted in a crucible (integral with the diecasting process) and injected into the mould chambers by a force pump mechanism, partially submerged in the molten zinc alloy through a hollow tube (the gooseneck).

THE BENEFITS OF DIECASTING

Strength and rigidity
Diecastings have a strength and rigidity unobtainable in all but the most expensive engineering plastics. Thin sections remain dimensionally stable with the minimum of reinforcement; thick sections do not exhibit sink marks.The ability to mould to close tolerances (± 0.05mm, ±0.002in), with complex features and thin sections (1.5mm min.), with a good surface finish, can substantially reduce time-costly machining and quality control operations, minimise wastage. Compared with forging, diecasting provides higher production rates, with less finishing.

Compared with plastics moulding, diecasting provides greater rigidity, strength, dimensional stability, no moisture uptake and high temperature resistance.

Quality and surface finish
Die castings can provide the ideal combination of fine and complex detail with good surface finish, suitable for plating, painting or fine powder coating.

Cost effective
Die casting provides a highly efficient component production method giving excellent cost/performance effectiveness for components – at both long and short production runs.

Fine surface finish, without voids, is ideal for powder coating, painting or chrome plating to excellent quality.

Die casting is a production method with a short cycle time, excellent repeatability and batch-to-batch consistency.

Is die casting right for your component?

         How do the benefits listed here apply to the needs of your components? It may be that your components would be better injection moulded in one of the wide range of engineering plastics and fillings (glass, carbon and steel fibres). GC Pressure Diecastings is able to supply totally unbiased recommendations since a sister company within the PC Cox Group is a major supplier of plastic moulding.

PMTOOLING has a full range of capabilities-from custom filter design to prototyping, validation, testing production volumes to fit your needs. PMT will help you bring your idea from concept to reality.

Partner with us early in the development cycle, and take advantage of our ability to optimize your screen filter design to maximize filtration and product performance. We even offer value-added services that can shorten your supply chain, like technical molding for plastic components, plastic welding, product assembly and thermoform packaging.

Through it all, a dedicated project management team will ensure you receive the efficiency and service you need to reduce your product development costs and accelerate your time-to-market.

Our advanced manufacturing processes allow us to create products in any shape or configuration from simple traditional components like mesh screens to highly complex devices like custom filters. We have the experience to take on whatever you bring to us – whether it’s building upon an existing design concept or providing a unique solution based upon specific performance requirements. We provide a comprehensive range of services including design, plastic mold making, prototyping, building, testing and plastic molding manufacturing to the market

With our experience in product development and design, we can help you establish your application requirements and translate your design ideas into a cost-effective component for your specific application.

It’s this proactive, solution-driven custom filter development that helps you achieve optimal results. From concept to finished product, you’ll receive a host of value-added plastic injection services that transl

ate into a superior product, a competitive price, and a low-variability product that meets spec in every respect.

We can use plastic or stainless screens in the plastic molding process. Depending on the size of the part a multi-cavity mold can be manufactured to increase production. Secondary post molding operations are sometimes required to complete the assembly. Don’t worry about finding the right screen filter for your part, our Sales Department will help find what you need.

Custom Plastic Molding

Custom plastic molding and Plastic Mold

Custom plastic molding is widely used for manufacturing a variety of parts, from the smallest component to packaging. It is used in a wide variety of applications such as filtration, industrial parts and appliances. Plastic Molded Concepts develops and produces a wide variety of products for low and medium to high volume quantities and we offer a wide variety of engineering grade resins.

We have had many experiences with customers that have brought their molds to us because they cannot get a product to reach the in-use durability the resin manufacturer promised. The previous molder was not aware of all the processing precautions and procedures that were required to make the resin perform to the manufacturers’ expectations. Our engineering group is very careful to study the resin processing requirements and to establish processing procedures to guaranty the proper resin and finished properties of the injection molded part.

Complicated part geometry, exotic engineered resins, and tight dimensional tolerances are areas that most injection molding companies would avoid. Cavity pressure monitoring and closed loop injection control are a must.

Whatever your custom injection molded parts needs, Plastic Molded Concepts will find your solution. We are experts in custom plastic injection molding. You can be confident that our processes will create precise plastic parts. For challenging injection molding processes, we will use our experience and skill to handle any challenge.

If you’ve ever experienced a catastrophic product failure caused by contamination, you’re intimately aware that there’s more to designing custom filters than simply fitting filtration within an allotted space.

PMTOOLING engineers are trained and experienced in the plastic molding development of innovative filtration and contamination control solutions for a broad range of commercial applications, including custom filters for drinking water and paint, small and large appliances, heavy equipment and recreational vehicles.

Our engineers think outside the box when it comes to filter and screen design, generating ideas that are both effective in controlling contaminants and cost-effective to produce. Our present customer list is but a few of the Fortune 500 companies.
