Core Technological Advantages

01
Leak and Airtightness Testing
From water leak testing of prototypes (first-off parts) to high-precision airtightness testing of finished products.
Utilizing high-precision differential pressure or flow-based leak detectors, we perform quantitative testing on sealed chambers and piping systems.
Employing specialized equipment—such as [Insert your airtight testing instrument brand/model here; e.g., 'ATS Series Automated Leak Detectors']—we provide precise leak rate data that far exceeds the sensitivity and reliability of traditional water-based testing methods.
We verify the long-term seal integrity of products under specified pressure conditions, thereby eliminating potential risks.
02
Density Test
By measuring material density, the correctness of the material grade is precisely verified, internal porosity is detected, and the quality consistency of the welded zone is evaluated.
Utilizing a high-precision electronic densimeter (such as [Insert your density measurement instrument brand and model here—e.g., 'Mettler-Toledo series densimeters']) and adhering to Archimedes' principle, it provides rapid and accurate density data.
03
Conductivity / Resistivity Testing
For semiconductor and high-purity applications, the content of residual ions in liquids is critical. This test directly relates to product cleanliness and chemical compatibility.
As illustrated by the device shown, we utilize a professional deionized water resistivity tester—such as the 4-electrode instrument depicted in the image—to precisely measure the resistivity or conductivity of water and other liquids, thereby ensuring the ultra-high purity of our cleaning solutions and the internal fluid pathways of our products.
04
pH Testing
Precisely measure the pH of contact liquids—such as cleaning agents, buffer solutions, or the carrier liquid for the product itself—to verify compliance with specified chemical environment requirements.
We utilize calibrated, laboratory-grade pH meters—such as the benchtop unit shown in the image—to provide stable and reliable pH readings that meet the requirements of quality control and process validation.

Welding

Composite Plastic Welding & Integration Processes | A One-Stop Technical Solution for Complex, Multi-Material Components

In the fields of healthcare and semiconductors, many core components cannot be manufactured through a single process. Instead, they are often integrated from multiple materials and components through a series of precision machining and joining processes.
CHawk's core competence lies in mastering the complete, integrated process chain—encompassing thermoforming, welding, machining, edge routing, bending, and bonding—to provide you with comprehensive solutions ranging from concept to finished product.
We understand the characteristics of different materials and, through past experience, avoid quality risks and communication costs associated with cross-supplier cooperation

Detailed Explanation of the Composite Process Chain

Precision Blister Forming

Role: To fabricate large, thin-walled, hollow shells or cavities that serve as the foundational structure for assemblies.

Capability: To utilize specialized sheet materials—compliant with medical and semiconductor industry standards—to provide a highly consistent substrate for subsequent welding and assembly processes.
Multi-Process Precision Joining and Welding

Function: To create permanent or high-strength connections between various components—such as thermoformed housings, machined parts, and bent parts.

Core Technology — Plastic Welding: Utilizing processes such as hot plate welding and fusion welding for medical- and semiconductor-grade materials (including PP, PP-CP5, PVC-C, PE, PVDF, HDPE, ABS, PFA, ECTFE, PTFE, etc.) to achieve the following:
• High Sealing Integrity: Applicable to fluid channels and gas lines, ensuring zero leakage.
• High Strength: Forms a permanent bond with strength comparable to that of the base material.
• No Leachables: A clean welding process that meets requirements for biocompatibility and high purity.
5-Axis Machining and Precision Edge Milling

Role: Performs post-processing on thermoformed or bent parts to achieve a level of extreme precision that cannot be attained through a single-stage forming process.

Application Scenarios: Machining Critical Features: Precisely milling sealing grooves, mounting holes, or sensor interfaces into housings. Precision Edge Trimming: Removing flash or refining contours on welded assemblies to ensure smooth edges, precise dimensions, and the absence of stress concentration points.
High-Reliability Bonding

Function: Serves as a supplementary or alternative process to welding, utilized for joining dissimilar materials or complex geometric structures that are unsuitable for welding.

Capabilities: Employs medical-grade or semiconductor-grade adhesives, utilizing automated dispensing and curing controls to ensure the repeatability of bond strength and cleanliness.
