We need brass parts with non-standard dimensions or a special design for our project. What is your production capability in this regard?
Yes, custom manufacturing is one of our core competencies. We can produce special brass parts with the tolerances required by your project, based on technical drawings or samples. Our engineering team can be your solution partner in all processes, from concept to mass production.
How long does your prototype production process take for a new product, and what are the stages of transition to mass production?
The prototype process varies depending on the complexity of the design and mold requirements. Generally, we aim to quickly present the first samples after design approval. Once the sample approval (including the PPAP process if necessary) is completed, mass production planning is carried out, and production begins according to the determined schedule.
What are your average production and delivery times?
Delivery times vary depending on the order quantity, product complexity, and current production intensity. While we generally deliver standard products from stock, we specify a clear lead time during the quotation phase for custom manufacturing projects.
What is your production and delivery capacity for high-volume or periodic orders?
We have structured our production planning to ensure uninterrupted supply to main industries and high-volume projects. We offer a guarantee of timely and complete delivery by creating a special production and stock plan for your annual or periodic orders.
Do you provide certification or traceability for the raw material (MS58 Brass) used in your products?
Absolutely. All raw materials we supply have conformity certificates according to international standards. We guarantee the raw material quality of every product by providing full batch-based traceability in our production processes.
What measurement equipment do you use in your quality control processes, and how do you track calibration?
Our quality laboratory includes precision measurement equipment such as profile projectors, digital micrometers, calipers, and special gauges. All our equipment is periodically calibrated and certified by accredited organizations.
What is your pricing policy? Do you apply special discounts for project-based or high-volume purchases?
Our pricing is flexible depending on the order quantity, the technical specifications of the product, and the duration of the cooperation. We apply competitive and special pricing policies for high-volume and project-based purchases. You can use our "Get a Quote" page for a detailed offer.
Can we request samples of your products to evaluate your quality?
Yes, we send samples to allow you to evaluate our quality and product compatibility, especially before mass production or project-based agreements. Please contact our sales team for sample requests.
What is your policy regarding intellectual property and design confidentiality? Do you sign a Non-Disclosure Agreement (NDA)?
We attach the utmost importance to the confidentiality of our customers' design and project information. We are ready to sign a mutually protective Non-Disclosure Agreement (NDA) before starting any cooperation.
Do you offer flexible logistics models such as "Just-in-Time" delivery or consignment stock management for your main industry customers?
Yes. We can implement "Just-in-Time" delivery models to ensure your production lines run smoothly. Furthermore, within the framework of long-term agreements, we aim to increase your supply chain efficiency by holding safety stock or developing consignment stock models for you.
Do you provide engineering support for converting an existing casting or multi-part assembly product into a single-piece hot-forged product (reverse engineering)?
Absolutely. This is one of our areas of expertise. By analyzing your existing part, we can redesign it as a single-piece hot-forged product that is more robust, less costly, and easier to assemble.
Do you offer surface coating options (nickel, chrome, etc.) for your products?
Yes, in addition to the standard brass surface, we offer various surface coating options such as nickel and chrome, depending on your project's aesthetic or corrosion resistance requirements.
According to which standards are the pressure resistance and burst tests of your products performed? Can you share the test reports?
Samples taken from our production batches are subjected to hydrostatic pressure and burst tests according to determined standards. Upon request, we can share the reports of project-based tests with our customers.
Does your company have quality management systems or industry certifications?
We conduct our production processes within the framework of internationally recognized quality management standards. You can contact us for detailed information about our current certifications and quality policy.
Do you provide export and logistics support for international projects?
Yes, we actively serve international markets. Our experienced team in export operations manages the customs clearance and logistics processes of your orders smoothly.
According to which international standards (ISO, DIN, etc.) are your products manufactured?
Our products are manufactured in compliance with relevant ISO and DIN standards, especially in terms of thread dimensions and material properties. If your project requires a specific standard, we can adapt our production accordingly.
What is your Minimum Order Quantity (MOQ) policy for orders?
Our minimum order quantity varies depending on whether the product is standard or custom-manufactured. While we can be more flexible for standard products, we determine a minimum quantity for custom manufacturing projects to cover mold and production preparation costs.
Do you provide technical drawings or 3D CAD files (STEP, IGS) with your products?
We provide basic technical information for our standard products in our catalog. In project-based collaborations and custom manufacturing processes, we share the necessary technical drawings and 3D models with our customers for approval processes.
Do you apply an additional stress relief (annealing) process to your parts after hot forging?
Yes, we apply controlled stress relief annealing for our parts that will operate under critical and high pressure. This process significantly increases the part's resistance to the risk of "season cracking" over time or under vibration.
What are your packaging and shipping standards? What precautions do you take to prevent damage to products during transport?
We carefully package our products to protect them against impact, moisture, and corrosion during transport. For high-volume shipments, we use standard industrial methods such as palletizing and stretch wrapping.
What is your product return or exchange policy?
In case of any defect or error resulting from our production, we fully stand behind our products. Our return and exchange policy is carried out based on customer satisfaction within the framework of the conditions specified in our sales agreement.
What is the surface roughness value (Ra) and thread profile tolerance range you achieve in your CNC machining processes?
We aim for a surface quality and precise tolerance ranges above industry standards on our sealing surfaces and thread profiles. We have the capability to manufacture in compliance with the specific Ra value and thread class tolerances required by your project.
What are your payment options and deferred payment terms?
Our standard payment method is bank transfer. In long-term and high-volume collaborations, flexible payment and deferred payment terms can be evaluated depending on the customer's commercial history and project size.
Do you provide after-sales support when we encounter a technical problem or have a question about the product?
Yes, we offer after-sales technical support service. Our engineering and sales team will be happy to assist you with any questions regarding the use or performance of our products.
Is it possible to visit and audit your production facility?
Certainly. In line with our principle of transparency, we are open to planned audit visits for our potential and existing customers to see our production facility and quality control processes on-site.
