WELPING is our primary brand, focusing on common-size plastic pipe fusion machines, large-diameter butt fusion welding machines, HDPE pipe fittings, and related tools.
Gruvmaster, as a dedicated sub-brand, specializes in providing various pipe grooving machines, pipe cutters, and other pipe processing and fabrication tools for metal piping.
With more than 200 machine structures and tools developed under his direction, Mr. Arron brings both experience and innovation to our engineering team. His work has shaped much of what we build today—and has been recognized by several international brands through successful roll grooving machine development and technical cooperation.
Arron has a strong focus on hydraulic system design, a key component in many of our grooving machines and tools. His systems are known for their reliability, clean layout, and long service life.
Most recently, he led the development of a fully sealed, integrated hydraulic pump—a major breakthrough in grooving machine hydraulics. The new design supports OnePush™ fast feed-in, and TitanSeal™ requires no oil change or maintenance for 2–3 years, and significantly improves overall system stability.
A constant learner, Arron draws insight from field applications, customer conversations, and leading designs in the market. He’s quick to spot the logic behind a good design—and turn it into ractical, forward-thinking solutions.

Flexible Endoscopes:Ideal for examining the gastrointestinal tract, respiratory system, and other areas requiring maneuverability.
Rigid Endoscopes:Suitable for procedures like arthroscopy and laparoscopy where a straight, sturdy scope is needed.
The length of the endoscope should be sufficient to reach the target area in small animals. The diameter should be appropriate to navigate through the anatomical structures without causing injury.
High-definition cameras and superior optics are crucial for clear visualization of internal structures.
The endoscope should be robust enough to withstand repeated use in small animals and flexible enough to navigate through their anatomy.
Check compatibility with necessary accessories such as biopsy forceps, graspers, irrigation and suction systems, and insufflators.
Consider the portability of the equipment, especially if it needs to be used in various locations such as farms or different veterinary clinics.
Ensure the availability of technical support and training for the veterinary team to effectively use and maintain the endoscope.
Evaluate the cost in relation to the features and benefits provided. Check for warranty and after-sales support to ensure long-term reliability and service.
With the increasing awareness of environmental protection, more and more catering customers are looking for alternatives to plastic. Disposable wooden tableware meets this demand, reducing the environmental burden.
With the increasing awareness of environmental protection, more and more catering customers are looking for alternatives to plastic. Disposable wooden tableware meets this demand, reducing the environmental burden.
Compared to plastic tableware, wooden tableware has a better texture and is more comfortable to use, enhancing the dining experience for customers.
Many countries and regions have already enacted or are enacting laws and regulations that prohibit or restrict the use of disposable plastic products. Wooden tableware complies with these regulations, helping catering customers avoid legal risks associated with using non-compliant products.
Using eco-friendly products helps enhance the image of catering brands, attracting consumers who are concerned about the environment and health, and increasing brand loyalty.
The use of plastic tableware causes severe environmental pollution, while wooden tableware is biodegradable and can effectively reduce plastic waste pollution, meeting corporate social responsibility requirements.
Wooden tableware does not contain harmful chemicals and does not release harmful substances during use, ensuring the health and safety of customers.
All our products are meticulously designed to ensure that at the end of their life cycle, they can be naturally decomposed by microbial activity in the environment, such as bacteria and fungi, into harmless natural elements like soil, water, or air.
