Custom fully gripper solution

In modern manufacturing environments, each product presents a unique handling challenge: from heavy and bulky engine blocks, fragile glass panels, and easily deformable cardboard boxes to electronic components requiring absolute precision. In reality, even the most powerful power-assisted lifting systems struggle to maximise efficiency without a custom fully gripper – precisely tailored to the shape, weight, and handling requirements of each specific product.

With its R&D and direct manufacturing capabilities in Vietnam, Vietmani offers tailor-made fixture solutions, personalised for each product and workstation, optimising safety, accuracy, and operational productivity.

What is a gripping for an industrial manipulator?

A gripping is a component attached to the end of the industrial manipulator, directly in contact with the product to grip, clamp, suction, rotate, or flip the lifted object.

Simply put, a fixture is an end device attached to the robotic arm that helps convert the power of the power-assisted system into precise, sophisticated operations, such as secure, correct, and safe holding.

Depending on the product's characteristics, the fixture can utilise vacuum suction (for flat surfaces), mechanical clamping (for hard, solid objects), or magnetic force (for ferromagnetic materials).

Why choose custom jigs instead of standard ones?

In manufacturing plants, assembly lines, and the logistics industry, products and goods come in many different shapes and materials. Therefore, using a single jig for everything is impossible.

Here are some reasons why you should choose custom jigs from Vietmani:

• Optimising compatibility with the lifting object's geometry based on accurate 3D drawings to create clamps that tightly fit the contours. This eliminates shaking, slipping, or falling due to an unstable centre of gravity.
• Absolutely protecting the surface of high-value products such as painted car bodies, glass panels, or electronic components by using specialised contact materials such as high-strength rubber, POM plastic, air cushions, or vacuum suction cups to prevent marks. This is something that standard metal clamps cannot provide.
  Integrated drive mechanisms enable complex movements such as rotation, flipping, and tilting.
• Each work position has different heights and operating distances. Custom jigs allow for the precise placement of handles and control buttons at the most convenient position for the worker's arm reach. This eliminates unnecessary operations, reduces muscle fatigue, and significantly increases work speed.
• Vietmani jigs incorporate intelligent sensor systems, such as sensors that detect when the clamp is secure before lifting, and position sensors that only release the clamp when the object has touched the floor. This increases equipment safety and protects workers even when they are tired or distracted.

Investing in custom jigs is not an additional cost, but an investment in safety, accuracy, and productivity. A precisely tailored jig will help the power-assisted equipment perform at 100% of its inherent power.

Types of Jigs and Fixtures Vietmani Supplies

At Vietmani, we understand that each handling requirement is a unique problem. Based on a solid R&D technical foundation, we offer 5 main lines of jigs and fixtures, which can be 100% customized to suit your specific production needs:

Mechanical Grippers

Mechanical grippers operate on the principle of using clamping jaws, hooks, or lever mechanisms to securely hold the lifted object. Thanks to this robust structure, mechanical grippers are particularly suitable for products with stable shapes, such as machine parts, engines, tyres, or wooden crates in workshops.

The reason this type of jig is trusted lies in its clamping jaws. They are usually machined from aluminium alloy or specialised POM plastic, which is both durable and smooth. More importantly, the clamping jaws can be flexibly customised to closely grip the product, holding it securely while ensuring no scratches, making the lifting, rotating, and moving process safer and smoother for the operator.

Vacuum Grippers

Vacuum grippers operate on the principle of creating suction using rubber suction cups, combined with a vacuum pump or Venturi vacuum generator. When the system is activated, the pressure is rapidly lowered, allowing the lifted object to firmly adhere to the gripper.

Thanks to this principle, vacuum grippers are the optimal solution for large, flat surfaces such as glass sheets, metal sheets, cardboard boxes, food packaging, or construction panels. These are materials that are difficult to clamp mechanically but are very suitable for vacuum suction.

The highlight of this type of gripper lies in its multi-point suction design on a single beam (manifold). This arrangement allows for lifting large material sheets while distributing force evenly, maintaining absolute balance and stability throughout the lifting, rotating, and moving process.

Pneumatic Grippers

Pneumatic grippers operate based on pneumatic cylinders, allowing the clamping mechanism to automatically open and close quickly with a large and stable clamping force. This ensures precise holding and releasing of the lifted object, minimising operational errors.

With their durable and high-speed operation, these grippers are commonly used in automotive and motorcycle assembly lines or in heavy metal handling, where continuous repetitive operation and high safety standards are required.

The most valuable feature is the integration of a smart control system directly on the handle. Operators only need a simple action to clamp or release the product in an instant, ensuring both speed and reliability throughout the work shift.

Tilting & Rotating Fixtures

Tilting and rotating fixtures are designed with integrated mechanical or pneumatic motor joints, allowing for proactive changes in the object's orientation during operation. Thanks to this mechanism, the product can be rotated or tilted to the desired angle without requiring manual effort.

This type of fixture is particularly effective in processes requiring 90° product tilting or 180° rotation, such as quality control, surface coating, or assembling components in the correct technical position. Operations that were previously labour-intensive and riskyhave now become easier and more precise.

A key feature is the meticulous calculation of the centre of gravity of the lifted object from the design stage. As a result, the rotational movement is smooth, stable, and free from vibration or loss of momentum, ensuring safety for both the product and the operator.

DC Tool Holders

DC tool holders are designed as integrated suspension frames, compatible with popular electric or pneumatic impact wrenches on the market, such as Bosch or Atlas Copco. This ensures the tool remains stable throughout the operation, allowing the operator to fully concentrate on the precision of each tightening.

This type of holder is commonly used in chassis and automotive engine assembly plants, where high precision and especially torque resistance are required. In these processes, even a small deviation can affect the quality of the entire assembly.

The biggest difference of DC tool holders lies in their ability to almost eliminate the recoil transmitted to the worker's hand. This not only protects the operator's long-term health but also ensures that every tightening position achieves the correct torque and technical standards, uniformly and stably.

At Vietmani, whether it's a simple fixture or a complex system, all undergo a rigorous 3D simulation and real-world load testing process before installation at the customer's factory. This is how Vietmani ensures that each solution not only works, but also operates safely, reliably, and accurately from day one.

Outstanding Advantages of Fixtures Manufactured by Vietmani

While many companies on the market only offer imported fixtures at high costs and with limited customisation options, Vietmani differentiates itself through complete self-reliance:

• 100% Control over R&D and Production: Vietmani possesses a team of R&D engineers specialising in mechanics and pneumatics, along with a direct manufacturing facility in Hanoi. This allows us to customise even the smallest details of the fixture to precisely solve customer problems, instead of trying to force customers to use unsuitable standard products.
• Prioritising High-Grade Aluminum Alloy Materials: An overly heavy fixture will reduce the sensitivity of the power-assisted lifting arm. Vietmani prioritises the use of high-strength aluminium alloy to manufacture the fixture frame. The result is ultra-lightweight yet extremely durable arms, helping the power-assisted system achieve the most responsive Zero-Gravity balance.
• Fast response time: If ordering jigs from overseas, you may have to wait 8–12 weeks. With Vietmani, the process from design to delivery only takes 2–4 weeks. Especially when customers need to change the design or upgrade the jig to suit a new product model, we can handle it immediately at our domestic manufacturing facility.
• Integrated multi-layered safety system: Vietmani jigs are not just purely mechanical. We integrate intelligent safety solutions such as pneumatic interlocks (prevent clamp release until it touches the floor), object detection sensors, and emergency braking systems. Each jig is designed to protect both the product and the operator in all situations.
• Multi-device compatibility: Vietmani jigs are designed with flexible connection standards. We not only install lifting arms manufactured by Vietmani (HA-Series, BENA) but can also design and integrate them seamlessly with international brands such as Indeva, Dalmec, or existing crane systems at your factory.
• Optimal Cost – Real Value: By eliminating intermediary costs, import taxes, and international shipping, Vietmani's custom jig service offers extremely competitive pricing.
