Introduction
Teknik Döküm is a Turkish manufacturer specialising in precision casting equipment for the jewellery industry. Their systems are built around two of the most labour-intensive and error-prone stages of the lost wax casting process — investment mixing and mould breaking — and engineered to make both faster, cleaner, and more consistent than manual alternatives.
Lost wax casting is the backbone of modern jewellery manufacturing. But the casting itself is only one part of a multi-stage process, and the stages surrounding it — investment preparation before the cast, and mould breaking after — are where inconsistency and inefficiency most commonly creep in. Teknik Döküm’s equipment addresses both, giving casting facilities better control over the full casting cycle, not just the metal pour.
NJTPL has been supplying Teknik Döküm casting systems to Indian jewellery manufacturers and casting facilities — providing genuine product access, technical guidance, and local support from Mumbai.

Why Investment Preparation & Mould Breaking Matter in Lost Wax Casting
Teknik Döküm machines solve both problems. Their systems deliver:
- Precisely controlled investment mixing under vacuum — eliminating air bubbles and ensuring consistent slurry quality every time
- Accurate water-to-powder ratios — removing the guesswork from investment preparation
- Automated mould breaking — faster, cleaner, and significantly less physically demanding than manual breakout
- Reduced casting defects originating from investment quality — fewer rejects, less rework, better metal recovery
- Improved workshop conditions — contained dust during both mixing and breakout operations
- Higher throughput across the full casting cycle — investment prep and mould breakout are no longer production bottlenecks
For Indian jewellery manufacturers and casting facilities running lost wax casting operations at any scale, Teknik Döküm equipment brings process control and efficiency to stages of the casting cycle that are too often left to manual improvisation.
Product Range
Vacumix Series
The Vacumix Series is Teknik Döküm’s investment powder mixing and pouring machine — designed to take the investment preparation stage from a variable, operator-dependent process to a controlled, repeatable one. The machine mixes investment powder and water under vacuum, eliminating air entrainment that causes surface porosity and mould defects in the finished casting. Once mixed, the slurry is poured directly into the flask under controlled conditions. The result is a consistently prepared investment mould — every flask, every cycle.
AWC-100D
The AWC-100D is Teknik Döküm’s investment breaker machine — designed for automated removal of investment material from casting flasks after burnout and cooling. Rather than breaking the mould manually with hammers or air chisels — a process that is slow, physically demanding, and risks damaging the casting tree — the AWC-100D breaks the investment cleanly and efficiently, releasing the casting tree intact. It significantly reduces breakout time per flask, improves piece recovery rates, and contains investment dust to protect workshop air quality.
Why Indian Casting Facilities Choose Teknik Döküm Through NJTPL
Better investment quality means better castings
The Vacumix Series removes the two most common sources of investment-related casting defects — air bubbles from inadequate vacuum and inconsistent mixing ratios from manual preparation. Fewer investment problems means fewer casting rejects and less remedial finishing work.
Faster mould breakout without piece damage
The AWC-100D replaces one of the most time-consuming and damage-prone manual stages in the casting cycle. Faster breakout, less physical strain on operators, and better intact recovery of fine and fragile pieces all directly improve production economics.
Process control across the full casting cycle
Most casting equipment investment focuses on the furnace and casting machine. Teknik Döküm fills the gap — giving facilities the same level of control over investment preparation and mould breakout that they already expect from their casting equipment.
Improved workshop safety
Both the Vacumix Series and the AWC-100D reduce the amount of investment dust released into the workshop environment during mixing and breakout — a meaningful improvement in working conditions on any production floor.

Frequently Asked Questions
What does the Vacumix Series do that manual investment mixing cannot?
The Vacumix Series mixes investment powder and water under vacuum, which removes entrained air from the slurry before it sets. Manual mixing — even with a vacuum chamber added separately — introduces more variability in mix ratio, mixing time, and vacuum application. Air bubbles in the investment create surface nodules and porosity on the casting surface. The Vacumix eliminates this by controlling all mixing parameters in a single, automated process.
What flask sizes is the Vacumix Series compatible with?
The Vacumix Series is designed to accommodate the standard flask sizes used in jewellery casting operations. NJTPL can confirm compatibility with your specific flask dimensions and advise on the correct model for your production volumes.
How does the AWC-100D break out the investment without damaging the casting tree?
The AWC-100D uses a controlled mechanical action to break and separate the investment material from the casting tree — rather than the impact forces of manual hammering, which transmit shock directly to the casting. This controlled action is far less likely to break fine sprues, bend delicate settings, or damage thin-section castings during breakout.
Is the AWC-100D suitable for both small and large casting flasks?
Yes — the AWC-100D is designed to handle the range of flask sizes commonly used in jewellery casting. NJTPL can advise on suitability for your specific flask sizes and casting tree configurations.
How much time does automated mould breaking save compared to manual breakout?
This depends on flask size and investment hardness, but automated mould breaking with the AWC-100D typically reduces breakout time per flask significantly compared to manual methods — and does so consistently across every flask, regardless of operator fatigue or shift length. NJTPL can discuss realistic throughput comparisons for your production volumes.
