Part Design & Feasibility Assessment

Many of our customers may not have CAD software or experience creating 3D parts from the ground up. To help, we offer design advice on plastic part designs, giving our customers the necessary guidance to create the part they need.

When you buy custom parts from us, we can provide you with tailored CAD drawing design support services. Simply send us your utilization needs and functional match criteria, and we will assist you in creating functional 3D models and 2D drawings.

If you provide us with product drawings, our experienced project team will carefully review your part design and material selection. We will evaluate the feasibility of the design and suggest any necessary changes. Our goal is to help you optimize the design and minimize the overall cost while maximizing its success. We are committed to ensuring that your design meets your requirements and achieves the desired results.

High Quality Material Selection

Precision molds are essential for manufacturing high-quality plastic products, along with the correct selection of materials.

When it comes to choosing the right injection molding material, there are several factors to consider. ABS, PC, PS, PET, PP, PA66, LCP, POM, silicone, and rubber are all common options.

With decades of production experience, RZD’s engineers are capable of recommending the best injection molding materials for you based on various factors, such as performance requirements, usage environment, and cost considerations. We also offer further treatment such as color masterbatch, flame retardant, foaming agent, lubricant, antioxidant, antistatic agent, and many more. Choosing the right material can help to:

High-quality plastics form the foundation of superior plastic product performance.
Avoid unnecessary design changes after your mold is manufactured.
Minimize the time it takes to process requests by improving operational efficiency.
Cut down on processing cycle times.

ABS is a commonly used thermoplastic material that boasts superior mechanical properties and a high impact strength. Its versatility makes it a useful material for a broad range of consumer products, including TVs, washing machines, refrigerators, telephones, computers, lamps, vacuum cleaners, fans, and air conditioners. It is particularly valuable for forming shells and parts of those products.

PC material is a type of polycarbonate plastic offering a range of impressive qualities:

PC material has an impressive level of transparency, with its clarity reaching over 90%, comparable to glass. Additionally, it is more resistant to impacts than glass and isn't as prone to breakage.
PC has exceptional heat resistance, with a capability to remain intact at 130°C or higher, exceeding the standards of ordinary plastic materials and demonstrating its suitability for use in high-temperature settings.
PC material has excellent cold resistance and can withstand temperatures as low as -40 ℃, making it a perfect choice for environments where temperatures tend to get low.
PC material has excellent corrosion resistance, offering robust defense against acid and alkali damage as well as chemical corrosion.
PC material has excellent ultraviolet resistance, meaning it won't easily turn yellow or become aged with prolonged exposure.
PC is an engineering plastic with superior mechanical properties. It provides excellent tensile strength, elastic modulus, and hardness, making it a highly reliable material for a range of applications.

PC material is utilized in many industries, such as electronics, automotive, and construction. The following are specific applications:

Electronics: PC materials are used to construct computer cases, displays, mobile phone cases, and other electronic items.
Automotive: Manufacturers of automotive components use automotive PC materials to produce a variety of parts, such as front windshields, lampshades, and interior components.
Construction material: PC material is utilized to create building materials like daylighting panels, soundproof insulation boards, security windows and more.
Medical: PC materials are widely utilized in the production of medical tools, such as surgical instruments, infusion bottles, and other medical supplies.

PS is an established plastic material boasting a proven manufacturing process. It has impressive transparency (88% - 92%), along with excellent surface gloss, easy dyeing, high hardness, and good rigidity. Additionally, it is resistant to water, chemicals, and is easy to process. Its broad range of utilities has made it a favorite for the optical industry, with applications including transparent or brightly colored parts used for lampshades and light fixtures. There is also the advantage of making electrical components and instruments that perform well in high frequency usage.

PET is a high molecular polymer with superior mechanical and chemical properties. It is very stable when exposed to heat, making it ideal for use in industries like electronics, medical equipment, and packaging.

PP is a milky-white, highly crystalline polymer that is non-toxic, odorless, and tasteless. Its lightweight feature makes it ideal for producing a variety of products, from basins and barrels to furniture, films, bags, bottle caps, and even car bumpers.

PA66 (Polyamide 66) is known for its high crystallinity, which imparts it with several characteristic properties. The high crystallinity of PA66 contributes to its rigidity and excellent heat resistance. These characteristics make it suitable for a wide range of applications.

PA66 is widely used in the manufacturing of components for machinery, automotive parts, chemical equipment, and electrical devices. Some common examples of PA66 applications include gears, rollers, pulleys, shafts, impellers in pump bodies, fan blades, high-pressure seals, valve seats, gaskets, bushings, various handles, support brackets, and wire coatings.

LCP (Liquid Crystal Polymer) is a new type of polymer material with various unique characteristics, including excellent mechanical properties, stability when exposed to differing dimensions and temperatures, impressive optical properties, chemical resistance, flame retardancy, and easy processing. This polymer material is widely used in sectors such as electronics, electrical, optical fiber, automotive and aerospace.

POM offers outstanding durability, strength, rigidity, as well as low water absorption. Unfortunately, it is not designed to withstand high temperatures and is prone to combustion and aging in the atmosphere. It is suitable for manufacturing wear-resistant mechanisms, transmission components, and parts used in various chemical and instrumentation applications.

Silicone rubber is an extremely versatile product with high adsorption, thermal, chemical, and mechanical stability. It is found in many industries and is most commonly used in:

Silicone is an essential material for producing various objects, including copiers, keyboards, remote controls, toys, and silicone keys.
Silicone is a versatile material that can be used as a reliable and resilient molding gasket, an ideal packaging option for electronic parts, as well as a reliable maintenance material for automotive electronic components.
It is useful for the fabrication of electronic components.
It can be applied in the production and manufacturing of kitchenware, as well as auxiliary kitchenware products.
Silicone is colorless, tasteless, and non-toxic, making it suitable for a variety of uses in the medical industry.
Silicone rubber can be used to produce conductive silicone rubber, medical silicone rubber, foam silicone rubber, and molding silicone rubber.
It is ideal for a variety of baby items- from maternity and infant products to baby bottles and bottle protective sleeves.
