FEATURES
Hard Power Infrastructure — Equipment That Clients Can See and Trust
Clients do not buy machines; they buy the outcomes that machines produce: precision, speed, and uniformity. Our manufacturing infrastructure is designed to eliminate variability before it reaches your production line.
Machining: Capable of Capturing 2-Micron Details
The quality of a mould ultimately determines the consistency of a cap. To achieve flawless part lines and mirror-polished surfaces on high-visibility cosmetic caps, we deploy a fleet of five-axis high-speed machining centers from Mikron, Makino, and Frank. This equipment can machine complex curved surfaces with an accuracy of 0.002mm. The client value? Your zinc alloy perfume cap or cylindrical dispensing closure arrives with a smooth, burr-free parting line, eliminating the need for costly secondary manual finishing and ensuring that the cap does not scratch or mar the bottle during high-speed capping.

- The mold manufacturing process and product material selection
Wire EDM: Precision for Micro-Features
Our slow wire cutting (Wire EDM) technology is critical for projects requiring ultra-fine details, such as 0.03mm micro-holes, narrow slots for tamper-evident bands, or intricate hinge geometries for flip-top caps. By executing these operations in-house, we avoid the thin-wall deformation common in outsourced machining, thereby reducing your scrap rate during pilot runs.
Injection Molding Machine Park: Scale with ±0.1% Repeatability
We operate 260 injection molding machines with clamping forces ranging from 30 tons (for precise small-dispensing caps) to 2800 tons (for large, heavy-duty cosmetic jar lids). Our fleet is dominated by all-servo electric drives, guaranteeing a repeatability accuracy of ±0.1%. For you, this means that the 100,000th cap coming off the line is dimensionally identical to the first, ensuring your high-speed automatic filling lines never experience a jam due to "out-of-tolerance" caps.

Validation: Eliminating the Guesswork with Metrology
Every mould shipped from our facility undergoes a full dimensional inspection. We utilize Coordinate Measuring Machines and optical imaging systems to produce a full dimensional report for each tool. We certify that critical process indices—specifically CPK values—are maintained at ≥1.33. This is not just a quality stamp; it is a guarantee of statistical stability that reduces your in-process QC burden.
Mould Manufacturing — Client Value from Lifetime and Lead Time
When clients ask about moulds, they are really asking: How long will it last without breaking? How much will it cost to maintain? And how fast can I get to market?
The Longevity Commitment
Using standard mould bases (P20) and premium hardened steel for cores and cavities (S136, 2344, 8407, SKD11, NAK80, H13), we deliver moulds with explicit lifespans. For standard plastics like PP or HDPE, we guarantee 1 million shots; for abrasive glass-filled materials, we guarantee 500,000 shots [8†L19-L20]. Every mould is accompanied by steel certification and a heat treatment curve. The result: you budget for the next 5 years of production without the "surprise" cost of mould repair.
Precision Tolerances
Standard structural features come in at ±0.05mm. For critical components such as threaded dispensing caps or flip-top hinges, we operate at ±0.005mm. This is the engineering difference between a cap that seals perfectly and a cap that leaks, damaging your brand reputation.
Lead Time Efficiency
Speed to market is critical in the volatile cosmetics industry. We have standardized lead times that reduce your risk of late product launches: simple moulds ready in 10 days; medium-complexity designs in 25-45 days. In emergency scenarios, we can expedite delivery while still maintaining rigorous T1 testing. We do not skip steps; we compress the workflow through parallelized manufacturing.
Advanced Mould Types
We are not limited to standard two-plate moulds. We deploy hot runner systems that eliminate runner waste, reducing material costs by up to 15-20%. For high-volume cylindrical caps, we utilize stack moulds to double output per machine stroke. For dual-material designs (e.g., a hard PP cap with a soft TPE seal), we have proven experience in multi-shot and over-moulding technologies.
Injection Molding — Solving Your Process Pain Points
The client‘s nightmare is variation: sink marks on a luxury cream lid, flash on a zinc alloy cap that requires expensive manual trimming, or inconsistent dimensions that cause caps to crack in cold weather.
Standardized & Connected Processes
To eliminate human error, all our machines are networked. Key parameters (temperature, pressure, speed, and cooling time) are locked within our Manufacturing Execution System (MES). Only certified engineers have authorization to make changes. We perform first-article and last-article inspections for every batch, ensuring that the parameter set at the beginning of the month is identical to the set at the end of the month.
Dimensional Stability & Warpage Control
Warpage is the primary enemy of cylindrical bottle caps. We counteract this through zone-controlled mold temperature controllers, keeping the temperature difference between core and cavity within 2°C. We back this with data: for a standard closure component, we have demonstrated continuous production across three weeks where the variation in a critical hole spacing was ≤0.02mm. For you, this means predictable assembly on your packaging line.
Appearance Grades
Depending on your market positioning, we deliver distinct quality grades:
Transparent Parts (Acrylic/PMMA): Zero bubbles, zero flow marks.
Electroplating-Ready Parts (ABS): No gas marks, ensuring a flawless metallic finish.
High-Gloss Parts: Surface roughness Ra ≤0.2μm, ready for hot stamping or silk screening. For printed logos, we guarantee registration accuracy of ±0.1mm.
Specialist Material Applications
We have industrial-scale experience with a vast range of engineering-grade polymers: PC/ABS, PC, PPS+40%GF, PEEK, PTFE/PFA, PA6+GF30, PBT, PEI, LCP, and Liquid Silicone Rubber (LSR). We provide material certifications for UL94 V-0 flammability and UV resistance up to 3000 hours, eliminating your compliance risk.
The Financial Logic: Cost Control without Compromise
Cost reduction is not about using cheaper plastic; it is about engineering waste out of the system.
Mold Flow Analysis (DFM)
Through advanced simulation using Moldex3D and Moldflow, we identify weld lines, air traps, and sink marks digitally before cutting a single piece of steel. This prevents expensive mould rework and shortens the debugging cycle from weeks to days, saving you 10-15% of the total project cost in development iterations alone.
Intelligent Manufacturing (Industry 4.0)
Our workshops are equipped for Industry 4.0 with automated material handling systems and real-time monitoring. We use ultrasonic wall thickness sensors mounted on the injection units to provide closed-loop feedback to the injection pressure, compensating instantly for viscosity fluctuations. This reduces the unit cost by minimizing scrap and energy consumption.
Logistics & Consolidation
We understand that managing a global supply chain is expensive. By offering end-to-end services—from mould development and material sourcing to high-volume molding, secondary decoration (spray painting, hot stamping, vacuum metallization), and assembly—we serve as a single-source supplier. This consolidation reduces your procurement management costs by up to 20%.
Full-Service Lifecycle Management
Early DFM Engagement
Before we finalize the quote, we provide a Design for Manufacturing (DFM) report. This includes draft angle recommendations, wall thickness optimization, and gate location suggestions. We tell you where the ejector pin marks will go before you approve the design, ensuring there are no "structural surprises" later.
Pilot Validation
We do not send you a mould without proof. We run small-batch pilot runs (100 to 500 shots) for your validation. We provide a full report on yield rate and CPK values, confirming stability before mass production begins.
Maintenance & Spare Parts
Every mould ships with a set of critical spare parts (ejector pins, core inserts). We schedule preventative maintenance every 200,000 cycles. For repairs, because we house our own electrode processing and EDM workshops, we restore production within 24 hours of a reported fault. This ensures your supply chain never goes dark.
