Mold design and manufacturing is a complex industrial work that requires very high levels of precision, care and experience. SPTECH has the most up-to-date design, analysis / simulation, production and testing infrastructure with its experience in injection mold design and production for more than 20 years.
Product
SPTECH considers a technical innovation, suitability for the purpose of use, simple geometry, economy, ease of use and moldability as the main principles of the design. Design is made in our offices by using computer-aided software (CAE) via customer expectations or direct technical drawings. At this stage, which is also called CAD Design, the suitability of the products to the design objectives is analyzed by using advanced engineering software (CAE / FEA / CFD) in order to detect potential problems in the molding and mass production stages and to identify possible errors and risks. In this way, both the production stage of the mold and the high costs that may arise during the mass production process are prevented. Parameters such as material flow, pressure drop, joint trace, gas cavities, filling time, temperature distribution, injection pressure profile, cooling time, 3D tensile analysis, 3D distortion analysis and runner design of the design are determined using Autodesk MoldFlows simulations. An important stage of product design for SPTECH is rapid prototyping. The prototypes of the products which are designed by CAD and approved for analysis are converted into printouts by using 3D printers in the design offices. In this way, potential problems that are not noticed at the design stage are realized in a concrete manner and our customers can examine and evaluate the product in its concrete form while it is still in the design stage. SPTECH is able to use reverse engineering opportunities from time to time in product design. Works with high precision CMM devices accelerate the product development stages and provide efficiency.
Mold
Mold design and manufacturing is a complex industrial work that requires very high levels of precision, care and experience. SPTECH has the most up-to-date design, analysis / simulation, production and testing infrastructure with its experience in injection mold design and production for more than 20 years. The design of the mold starts by analyzing and evaluating the customer requests and expectations in detail. The design stage is the most important stage among all stages, and a wrong decision can lead to serious costs. Fundamental issues such as production information, cycle time, investment budget, mold cavity, number of cavities, number of layers (for stack mold dies), moving cores, runner and pusher type, cooling system determined at this stage. Mold design is projected as a solid model by taking into consideration many important factors such as healthy processability of the mold parts, mountability, suitability of injection molding machine and easy intervention on the machine. Designs, static force, flow, filling and temperature analysis are made by using auxiliary engineering software (FEA / CFD).
SPTECH has been providing professional services in the production of single-layer and two-layer molds for the plastic injection industry since 1996, and thanks to its years of experience and design and manufacturing technology, it is unrivaled in the development of thinner wall products/molds compared to other organizations in the sector. SPTECH uses advanced high-tech CNC machines and measuring devices (CMM) with 3 - 5 axes to improve machining precision, shorten the processing process and provide the earliest delivery date in production.
Mold
The process from the idea stage of the desired product to the mass production is the mold production. Mold production with direct effect on the final product is a production process that requires CNC (Computer Numerical Control) machines which require precise and technical workmanship, modeling, drawing and processing in computer environment with advanced technology software and shaping steel with 0.005 percent of 1 mm. At SPTECH, mold production is made on high precision machine tools with the experience gained from the rich knowledge of the past years, and every stage of production is continuously controlled by high-tech precision measurement and control equipment (CMM). The environment in which the mold is produced is in a completely enclosed and controlled environment which is specially conditioned at +22 °C. Each part which forms the mold is checked through the relevant production stages in accordance with the prepared production schedule. Ultimately, all the parts forming the mold are mounted (assembled) and have a mechanical structure to be opened and closed.
Quality
Measurement controls of the parts forming the mold are made with CMM measuring devices. The measurements are carried out with high precision both during production and before assembly. With the approval of the measurement controls, the mold mounting (assembly) process begins. After the mold mounting process, pressuring tests are started.
Testing and
The molds we produce are tested by being coupled to injection molding machines within SPTECH. Test suitability to the project, tightness test, strength test and performance measurement checks (cycle time, product weights, etc.) are performed. The results of the test samples and production parameters are evaluated together with our customers and approved. After the test results are approved, the mold is subjected to final checks, documentation for use is prepared and delivered to the customer. When necessary, the mold is tested again at the customer's own workplace. The results are approved, mold usage and routine maintenance trainings are applied to the users and the mold is commissioned and delivered to the customer.
With our R&D center consisting of 2700 m2
SPTECH also offers modification and maintenance services for molds and automation systems according to the demands of our customers.
