Seven aluminium grades covering 280 to 3,200 t. One workhorse that most plants can start with, a heavy-duty variant for deep-cavity structural work, a premium high-temperature grade, and zero-silicone options for parts that go on to plating or anodising.
Dilution values marked with an asterisk are confirmed per application by the factory during the trial. We publish the conservative value and never over-promise a mixing ratio.
| Model | Position | Dilution | Typical use |
|---|---|---|---|
| ZP-418 | Workhorse | 1:120 – 200 | General aluminium castings across 280–3,200 t |
| ZP-418A | Heavy-duty | on request | Deep-cavity structural parts, clutch and transmission housings |
| SP-718 | Premium / high-temperature | on request | New-energy structural parts, hot dies |
| SP-618 | Standard | on request | General production |
| SP-518 | Economy | on request | Cost-driven general castings |
| ZP-316 | Oxidation-critical | on request | Pure aluminium, anodising-bound parts |
| ZP-318 | Specialty | on request | Charging-pile housings and similar |
ZP-418, at 1:120–200. It is the grade most plants should trial first, because it covers the widest band of wall thickness and die temperature without needing a bespoke formulation.
Clutch and transmission housings, structural nodes, anything with a long core and a deep cavity: ZP-418A. Deep cavities are where a marginal film turns into soldering.
New-energy structural parts and hot dies push the die surface temperature up and shorten the film's life. SP-718 sits at the premium end for exactly this.
Plating, painting, anodising: the grade must be silicone-free. ZP-316 is the oxidation-critical grade for pure aluminium and anodising-bound work. Why it matters →
On a heavy-duty grade running deep-cavity automotive housings, one customer measured their own numbers after switching: the die cleaning interval moved from 7 days to 21 days, and combined production cost — consumable, cleaning and downtime together — came down by roughly 25%.
Those are their measurements, not our claims. That distinction matters, because the number that decides a purchase is the one your own team records on your own machine. See how the case data is labelled →
Plunger lubricants — black, white and translucent white. Tell us which colour your shop uses and we match the grade. Granular salt — refined industrial salt for die and furnace-side use, with MSDS, shippable with your sample. De-slagging agents — de-oxidising and de-slagging products, traditionally used by Taiwanese and Japanese foundries.
One supplier for the die face and the plunger means one freight leg, one set of documents and one conversation when something goes wrong.
The questions buyers actually ask before the first drum. Answered without marketing language.
ZP-418 is the workhorse: factory-confirmed dilution 1:120–200, general aluminium castings across the 280–3,200 t range. ZP-418A is the heavy-duty variant for deep-cavity structural parts such as clutch and transmission housings.
The SP series sits at the premium end. SP-718 is positioned for high-temperature dies and new-energy structural parts, SP-618 is the standard grade and SP-518 the economy grade for cost-driven general castings. If you are casting thin walls at high die temperature, start the conversation at SP-718 rather than at the workhorse.
Yes — ZP-316 is the oxidation-critical grade for pure aluminium and anodising-bound parts, and we offer zero-silicone options across the range. Silicone carried onto the part interferes with anodic coating growth; for anodised work the grade must be silicone-free, not tested and hoped for.
Because the number depends on your wall thickness, cavity depth, die temperature and water hardness. A single figure would be a guess dressed up as a specification. We publish the conservative range the factory will stand behind and fix the final value on your machine during the trial.
