Custom Low Pressure Metal Press Molds – Precision Manufacturing for Household Aluminum Die Casting Parts

These custom low pressure metal press molds are designed for precision manufacturing of household aluminum die casting parts using low pressure die casting (LPDC) technology. Unlike high pressure processes, LPDC fills the mold cavity gently with controlled air pressure, producing parts with exceptional density, minimal porosity, and fine surface detail. Each mold is built from heat-resistant steel, featuring optimized risers, gates, and cooling channels to promote directional solidification. Ideal for producing medium‑volume runs of home appliance components, decorative hardware, and kitchenware, our low pressure molds deliver consistent part quality, pressure tightness, and extended tool life while keeping per‑part costs economical.

Features

1. Low Pressure Optimized Design – Runner and gate layouts tailored for laminar metal flow, reducing turbulence and oxide entrapment common in household aluminum castings.

2. Precision Cavity Finishing – CNC‑machined and polished cavities produce smooth, ready‑to‑coat surfaces for decorative household parts.

3. Heat‑Resistant Tool Steel – Molds manufactured from H13 or equivalent, vacuum heat treated to resist thermal creep during repeated low pressure cycles.

4. Effective Riser Placement – Strategically located risers feed shrinking sections, eliminating internal voids in thicker cross‑sections of sink strainers or cookware bases.

5. Tryout & Process Tuning – Each mold is tested on an LPDC machine with customer‑specified aluminum alloy, and sample castings are inspected for density and finish.

Our Advantages
1. We are the biggest lost foam mould manufacturer in China, we focus on high challenge lost foam mould and we have large gantry machining centers,30 sets imported high speed machining center,more than 40 sets general machine tool equipment;
2. We have 36 senior mould designers, to ensure reasonable / safety / high efficiency mould design and ensure the fast mould delivery and rational mould structure, make the process more safer and the production efficiency more higher;
3. We using numerical control machine tool to manufacture the mould cavities, to ensure a even thickness ;
4. We using ZL104 Aluminium to casting the mould, to manufacture a high strength mould;
5. For the big mould, we using Ø22*1 copper tube as cooling pipe, with water spray system, to get a nice cooling effect;
6. We Have (TEF10N) coating on the mould surface, it can reduce the friction, anti water/static electricity/acid-base/high-temperature, with this we can ensure the pattern has smooth surface without distrotion, and easy to demould;
7. All the screws we using stainless steel screw, easy to disassemble during maintenance;
8. For the big mould chest, we using 18-20mm thick wrought aluminium plate, to offer high strenght cavity.

Product Process

The research and development center is consist of 36 designers who are expert in 3D design, mold design, NC programming craftsmen, lost foam casting craftsmen and so on. We provide a full range of design and services for you. We discuss the mould process and confirm the scheme with your engineer together, this can guarantee the mould structure more reasonable more safety and more efficiency. We finish the product model and detection through reserve scan and 3D Coordinate Measuring technology to make sure each customer satisfy their mould.

Applications

• Kitchen Cookware Bases – Thick‑bottomed aluminum frying pans and saucepots requiring even heat distribution and warp‑free geometry.

• Household Water Filter Housings – Pressure‑tight enclosures for under‑sink or countertop water purifiers, cast with smooth interior surfaces.

• Decorative Furniture Handles – Aluminum pulls, knobs, and escutcheons with fine detail and plating‑ready surface finish.

• Small Appliance Frames – Structural bodies for blenders, coffee makers, and toasters, balancing strength and lightweight construction.

• Bathroom Fittings – Soap dispensers, towel bar brackets, and robe hooks cast in aluminum alloy for corrosion resistance and aesthetic coating.
