Product Description

Crida's silicone vacuum casting plastic parts have significant advantages in product development and small batch production. Its process is unique and widely used.

In the manufacturing process, the first step is to create a prototype of the part, which can be completed by 3D printing or CNC processing. The high precision of the prototype is the basis for subsequent production. Then make a silicone mold, pour liquid silicone into the frame around the prototype, put it into a vacuum machine and oven for curing, cut the mold and take out the prototype, and you will get a silicone mold. Then, inject the mixed polyurethane resin and other plastic materials into the mold under a vacuum environment. Under the action of vacuum, the material can fully fill every corner of the mold, effectively eliminate bubbles, and ensure the accuracy and quality of the parts. Finally, put the mold into the oven to accelerate curing and molding. After taking out the part, cut off the gate, remove the flash and other post-finishing work.

The plastic parts manufactured by this process have many advantages. In terms of precision and surface quality, it can achieve high-precision replication, high dimensional accuracy, smooth surface without defects, and can accurately restore prototype details to meet application scenarios with strict requirements on part precision; the cost advantage is outstanding. Compared with traditional injection molding, which requires expensive metal molds, silicone vacuum casting does not require this step, which greatly reduces production costs and is suitable for projects with limited budgets; the production cycle is also short, and the conversion speed from design to finished product is fast, which can quickly respond to market demand and meet small batch and fast delivery orders.

In terms of application areas, Crida's silicone vacuum casting plastic parts cover a wide range. In the automotive industry, it is used to manufacture automotive interior parts, component prototypes, etc., to help the development of new automotive products; in the electronics field, it can make electronic equipment housings and internal structural parts to meet the electronics industry's demand for rapid product iteration; in the medical field, it is used to manufacture customized parts for medical equipment to meet the medical industry's requirements for high precision and safety of products.

Features

1. High-precision replication: Creating silicone molds based on 3D models can accurately replicate prototype details with high dimensional accuracy, generally up to ±0.3% (the lower limit is ±0.3mm when the size is less than 100mm), ensuring that the parts are highly consistent with the design requirements.

2. Good surface quality: Material infusion under vacuum conditions can eliminate bubbles, and the surface of the parts is smooth and defect-free. It can meet the surface quality requirements of most application scenarios without too much post-processing.

3. Diverse material selection: A variety of materials such as polyurethane resins can be used to meet different design requirements, such as different temperature requirements, surface textures, hardness, etc., and you can also choose to make all opaque, translucent or completely transparent parts.

4. Short production cycle: From creating a prototype to producing a part, the entire process is relatively fast. It can usually be completed within a few days, which greatly shortens the product development and listing cycle compared to traditional processes such as injection molding.

5. Cost-effective: No need to make expensive metal molds, only silicone molds need to be made, and silicone molds can be reused many times, which reduces mold making costs and material consumption, and is suitable for small batch production.

6. Strong design flexibility: Molds can be created for products of any size or shape, and parts with complex designs or functions can be produced, such as parts with textured surfaces or small parts, which is difficult to achieve with some other processes.

Technical Parameters

Applications

Silicone vacuum casting plastic parts play a key role in product development with their unique process advantages. In the product prototyping stage, companies can quickly transform design concepts into physical models, verify the appearance, structure and function of the product through actual samples, and promptly discover design defects and improve them. For example, when developing new models, automobile manufacturers use silicone vacuum casting plastic parts to make prototypes of interiors, lights and other parts to accelerate the product iteration process and shorten the overall R&D cycle.

In the field of small-batch production, silicone vacuum-casting plastic parts have significant advantages. For products with small market demand or high degree of customization, traditional large-scale manufacturing methods are too expensive, while silicone vacuum casting does not require expensive metal molds, which can greatly reduce production costs. For the production of niche electronic products, high-end customized accessories, etc., the use of this process can not only ensure product quality, but also flexibly meet the diverse needs of customers, and achieve a balance between economic benefits and product quality.

In professional fields such as industrial manufacturing and medical care, silicone vacuum-casting plastic parts are also indispensable. In industrial manufacturing, it is used to produce mechanical parts, equipment casings, etc., and ensures equipment performance and reliability with high precision and good surface quality; in the medical industry, it can be used to produce medical device parts, customized medical auxiliary equipment, etc., meeting the strict requirements of medical products on material safety and dimensional accuracy, and providing strong support for medical technology innovation and personalized patient treatment.

Packaging and Shipping

1. Packaging protection: First, use anti-static bags or pearl cotton to wrap the parts individually to avoid surface scratches and static damage. For precision or fragile parts, customized EVA lining or foam compartments will be added. Secondly, put the individually packaged parts into corrugated boxes and fill them with cushioning materials (such as bubble film, styrofoam particles) to ensure that there is no shaking inside. For large parts, use wooden boxes for packaging, fix them with straps or bolts inside, and reinforce them with angle irons outside.

2. Labels and documents: Clearly mark the part name, model, quantity, weight, size and other information on the outside of the package, and affix warning labels such as fragile, moisture-proof, and upward. At the same time, prepare complete shipping documents, including commercial invoices, packing lists, certificates of origin, and compliance certification documents (such as CE, FDA, etc., provided according to product use and destination requirements), and seal copies of the documents separately and place them in the packaging box, and the originals will accompany the goods.

3. Logistics and customs clearance: Choose a logistics method based on customer needs and part characteristics, such as DHL, FedEx and other international express (for small items, urgent orders), or sea freight LCL/FCL (for large quantities of goods). Confirm transportation requirements with the freight forwarder or logistics company in advance, and purchase sufficient freight insurance. After shipment, promptly provide the customer with the waybill number, logistics tracking link and estimated arrival time, and assist the customer in handling customs clearance matters to ensure smooth delivery of parts.
