Strict Inspection

if need


After a thorough inspection, we will deliver your products to you as quickly as possible while ensuring their safety.

Surface Finishes of Injection Molding

Injection molding includes injection mold tooling, plastic injection molding, and more. The surface treatment of the mold is usually completed during the production process. After the injection molding is completed, we will carry out certain surface treatments on the finished product as per your requirement.


A grade finishes are made using a diamond buffing process and yield shiny and glossy surfaces on injection molded parts.


B grade finishes use grit sandpaper to produce parts with a slightly rougher finish than grade A parts. Custom molded plastic parts that undergo B grade finishing have a matte surface texture.


C grade finishes use grit sanding stones to produce a rough, uneven surface. Injection plastic parts that undergo C grade finishing have a matte surface texture.


D grade finishes use grit and dry glass beads or oxide to produce a very rough textured finish. Depending on the type of material used, products can have a satin or dull finish.

Frequently Asked Questions

Our mold-making process includes 6 steps:
Step 1: Production arrangement: Determine all of the requirements and arrange the production.
Step 2: DFM report analysis: Provide free but detailed production DFM report for further feasibility analysis.
Step 3: Production the mold: Put the mold into production and provide the Tooling Schedule form for the whole cycle for clients to check the process at any time.
Step 4: Free sample to test: Put the mold into production and provide the Tooling Schedule form for the whole cycle for clients to check the process at any time.
Step 5: Mass production:Client confirms the samples are qualified, then officially proceed with the subsequent production.
Step 6: Mold saving: Production is completed and delivered after quality inspection. Mold will be cleaned and properly stored for the next round of parts production.

Tolerance is very important, and if not correctly specified and controlled, assembling will fail. RapidDirect uses ISO 2068-c standard for injection molding tolerances unless tighter tolerance required.
No minimum order quantity, but the oder pricing will be more competitive if qty is higher.
After you place order, it takes about 35 days for mold designing and making, and more 3-5 days for molded parts production.
Generally, we generate the quote after our platform must have considered several factors, including the size of the component, mold complexity, number of injection cavities, materials, post-processing needs, etc.
Molds are normally created to duplicate plastic and metal parts. After testing the prototypes and the market, it is the most cost-efficient way to launch your products at scale.
Generally speaking, making plastic or metal molds (and moldings) is cheaper in China than other countries. But shipping costs should also be considered: you will need to use air freight if you have a tight schedule; sea freight is much cheaper, but will usually take 40 days or more.
A well-made, fully harden steel mold may be used for up to a million shots or injections, depending on the mold shape and injection material. Aluminum molds are less durable, which is good for short-run production with tight schedule.
Molding designs should avoid sharp corners, inconsistent wall thicknesses, and other features that restrict material flow.

Whatever you decide to use, in the end, what is the best cost-efficient way to get your parts done in the required quality is the key.
